I can’t play or make servers

So I’m having this issue where whenever I try joining a random server or searching one up, it says I need to update the game or check my internet. My internet is fine, but this keeps happening. It also does this when I make a server. Any help? I’m on an apple device. (iPad air 2) please, I really need this. It also happens on my phone (iPhone 13) ANY HELP?
Edit since I can’t reply: it doesn’t work no matter what servers are full. Every server could have 8 ppl snd I wouldn’t be able to join. It just doesn’t work even when I delete and download the game

You’re not alone.
