I am an Android 9 and my friend is on Android 10. some days ago Quick Share tile disappeared from his phone and yesterday evening it was gone from my phone too. I saw quick share in Google settings yesterday morning in my phone. I also checked the Google settings in his phone but it was not there. is Google removing quick share from our phones because it was not very reliable?
I have it on Android 13, albeit badly patched. Maybe older versions have a critical security bug in the implementation, for which they need longer than the disclosure time to fix or are unable to do at all?
