The game lags on my iPad Pro

The game seems to lag lot on my iPad Pro 2020. I had a word with Apple Support regarding the same too but they told me that I should contact the App Developer in order to get some resolution for this issue. The game should be running at a promised 120 FPS but i am not even getting 30. Please help me out with the same. I have already uninstalled and reinstalled the game and even formatted my iPad 2 times in order for the game to work properly.

 

The issue:

• The Game lags when I open any world.
• The lag increases when I start flying.
• Eventually I start getting frame drops and the game either freezes or crashes.

I have the screen recordings with Me but I am unable to attach them as the administrator has set the file upload limit to 10 MB only.
