Finally with UE 5.5.4 I’m able to build and get verified in Google play for Games v2 SDK usage
Google play is happy now & me too!
You would need to modify few lines in Google Ads APL file for the build issues, if you have it with UE 5.5.4
File : UE_5.5\Engine\Source\Runtime\Advertising\Android\AndroidAdvertising\AndroidAdvertising_APL.xml
Use _activity instead of _activityContext for runOnUiThread symbol not found
