For the past two days one of my friends hasn't been able to join my world. (Its not a realms world)

Its definatly on 1.17.10. Perhaps my world is too big (208.9MB) for him to enter on a switch??

Because it always gets stuck on the locating server loading screen for him.

If you find out this is just a technical issue (but I do know we have good WIFI) then I'm sorry for wasting your time (I know your very strict on rules and stuff) But I thought I would put this on here just in case.
