OS list
iOS 14, 15

BTW, our app don't support iOS 12 or below

Keeping it open for further insights from the team.

It seems to be related to the AccessibilityBridge.

Probably related to #96851 which has been fixed on master

Should be fixed in flutter-team-archive/engine#28495 which should be in 2.10.1

Closing as fixed.
