Answer 1

Your compileSdkVersion is low try to increase it to 33 to do this:
open the android/app/build.gradle file in your project, and find the android block. Inside this block, you should see a compileSdkVersion setting. This setting specifies the version of the Android SDK that your app is built against. The error message indicates that you need to update this setting to a higher version (currently 33) to fix the issue.
android {
compileSdkVersion 33
// Other settings here...
}
and rebuild your app
