Call of Duty mobile on my iPad keeps crashing

Hello!

First of all, I'm sorry for my mistakes on English.

I have an iPad 9.7 (6th generation) and Call of Duty mobile crashes in Battle Royale every time.

How I tried to fix that:

• I've deleted and installed the game
• I've deleted almost all the apps on my Ipad except Call of Duty mobile
• I've restarted my iPad before game
• I've used cpu-x and cleared up cache
• I've tried not to download files of maps and soldiers in a game
• I've updated iOs and game
• I've tried to change graphics in Call of Duty mobile to low

And nothing helps! Every time when I play in Battle Royale my game crashes and I have to open the game again.

I would appreciate if you can help me with that.

Thank you!
