Performance in iPad ninth generation, 2021 model has been decreased So bad.

Whenever I do simple browsing in my browsers like Safari or Brave, like when I use Twitter or something like that device freezes or starts lagging on its own and the other app which is open in the background is also closed immediately. more problems like Siri doesn’t respond many a time when using voice command, Before the January updates there was no such problem. Hope Apple fixes it :)
