Can't play with friends

Dear Minecraft team,

In the recent update of 1.16.100 I was trying to play on a world with my friends, but it said that I needed wifi to play with them. After this I checked if I could connect to a server. This did not work either for the same reason. This would be fine if not for the fact that I don't have wifi where I live. Also when going into a world that is multiplayer it says that multiplayer is turned off and that I can't invite people. This seems to be only affecting people playing on Android as one of my friends is playing on IOS and the other plays on the playstation 4 and both are able to play with each other. I hope this is an easy fix.

Sincerely,
