Hololens Video recording not showing UI elements

We're working with the Hololens 2 and sadly when recording a video, taking an image or going into the live-view, Unity UI elements are not shown in the image/video.
Does anybody know how we can make Unity UI elements appear in video & photo capture in Hololens?
Here is an example where below the title there is text present, but not captured in the image.
The title part uses a TextMeshPro component, while the text part uses a TextMeshProUGUI component (due to the scrolling window of the text.)
We're using Unity 2020.3.6f1, MRTK 2.7.2 with OpenXR backend.
Thanks for any help and recommendations.
For how to create mixed-reality photos and videos, you can use the Start gesture to go to Start, then select the Camera icon, for more information please refer to this link: Create mixed reality photos and videos.
If you want to seamlessly integrate mixed reality capture and insertion into your apps, you need to enable the Windows Mixed Reality Camera Settings provider in your MRTK profile and check Render from PV Camera.
The issue was that our Unity version was not updated, as hinted out in this github issue. Simply updating to the newest Unity version solved the problem.

UI Elements Not Rendering Properly on Android

In my game, UI elements not rendering properly on an Android device.
But it working properly within Unity Editor.
Here is the example of this problem I am facing:
I have purchased old source code and then upgraded its source code to Unity 2018 version.
I have implemented a Canvas based UI system from scratch and completed all UI screens.
At last, I have run the game in actual Android device but I was shocked by getting above result.
I have checked all things as per my knowledge but all properties values are proper.
Here you have one object selected to show its inspector.
So please give me some suggestion to correct above problem.
Make sure the UI/Default shader is present. Project Settings > Graphics > Built-in Shader Settings

How to remove unity build-in loading screen in Facebook instant game?

I am working Facebook instant game using unity2017.2. I deployed build for Facebook and uploaded it on Facebook. Everything is fine but when instant game start there is unity loading bar appears which take 8,9 seconds even if you have just one scene with one button in your game. So how can i remove that build-in unity loading screen. Please help. Thanks

It is not possible to skip the whole loading screen. As mentioned in the comments you can modify your UnityLoader.js - you can find this script in the Build folder of your build.
To read the code I recommend this beautifier
I just opend my build and found the object Progress in line 1849. Perhaps you have a different version and it is at a different line. Search for Progress
Here you can see what Unity is doing. In the Progress.update they are updating the ProgressBar.
At all it is not easy to read.
The easy way to customize you loading screen is to replace the graphics under TemplateData - here you can copy your own pictures. The names have to be the same as the original filenames: (default is light)
progressLogo.Light.png
progressFull.Light.png
progressEmpty.Light.png
I think this could be a solution for you?
Yup, it's a little bit frustrating to see a logo for a long time. I've worked on Unity version 2018.31f, and there, it's easily removable if you are using Unity Pro.
To remove the logo in Unity Pro, open your Unity WebGL project, Go to File -> Build Settings -> Player settings. You'll see settings for WebGL and a Splash Image column in that window, as shown in this picture.
As you can see in Splash Image settings, show splash screen column is inaccessible for me to tick/untick. The same goes with Show Unity Logo. This is because I'm currently using a free version of Unity. But in the Unity Pro version, you can untick this option and make that Unity Logo screen hidden.
If you are using the Unity free version, ensure a minimum Logo Duration of 2-sec, at least in the accessible version of Unity.

When I install apk on android, one scene is black. How to fix it?

So, I made my game for Android device and I've got a menu, store, info scene and a main scene. The main scene is where I play the game. But when I hit start on the menu it loads the "MainScene" and all I can see is the GUI but nothing else. I can collect items but the scene is just black (except the GUI).
I tested out with a web player and everything was fine then changed to Android and after I installed it (several times) I looked at the black screen.
How to fix this?
(I'm using Unity 4.6.1)
Can't comment, not enough rep.
Anyway, there are lot of things that can cause a black screen to happen on Android. Here are a few to look at -
Be sure your camera is not getting deactivated (in your case maybe not).
Are you using any plugin that is using alpha channel or stencil buffer?
Any other plugin that may causing this, disable them to check.
Is your 24/32 bit buffer ticked/not on build settings?
Double check your camera settings, lighting.
Stripping level to disable and rendering path on build settings etc.
Check the game on another device.
Provide more info about the scene here
There's definitely something on that specific scene.
