I was playing Minecraft Education Edition and I was trying to join a world, but it said this: "Join Codes are not available right now. Check your internet connection." I went into one of my own worlds and it said the same thing. 

I assumed this was just because of the internet connection, and that it just adjusted with their home network, but then the same thing happened to me. I started to get really confused, and I have no idea what's going on. 

Then it got worse. About two weeks ago, both iPads said this when we tried to sign out and sign back in again: "Could not find account. Check your internet connection." 

I have no idea what's going on, and I need help. Any suggestions?
