[2021] iPadOS performance slowdown

Hi everyone,

I noticed in these days a drastic drop in performance on iPad (Air 2020 - 4th gen).
Randomly, the game slows down and freeze for several seconds. Then everything's back to normal. Sometimes the game gave me server errors, so I started investigating on my connection, but I have a 1GB internet contract, with a tested download of 380MB and an upload of 130MB - with a ping of 5 - so I don't know what to think. No other background processes like updates and the OS recently updated.

Are any of you experiencing the same problems? I searched here in the sub-reddit but it seems happening only to me.
