can't join any servers and realms and we can't even play most pre installed servers

I recently updated our minecraft pocket edition to 1.20.81.01 and since then i can't join any servers and realms and we can't even play most pre installed servers,whenever I try to join servers the message pops up that unable to connect to world and sometimes Disconnected from server, so please fix this issue so i can play with my friends again, thank you
