I have got this reported under an ANR error in my Google Play Console.
I'm using Ironsource network and Facebook ads mediation. I tried everything but have no clue.
Here is all the stack trace I got from the Console:
Input dispatching timed out (Waiting to send non-key event because the touched window has not finished processing certain input events that were delivered to it over 500.0ms ago. Wait queue length: 2. Wait queue head age: 5971.9ms.), VisibleToUser
