Disconnect when attempting to preform a friendly challange

Exactly as the title says I guess.

This happens if I start the challange, or if my friend does.

Happens after a few of the loading bars fill, and then it just goes to “You have been disconnected”

This doesn’t happen on regular matches, only friendly ones.

EDIT: Now happens during regular matches as well. Doesnt seem to affect my rank.

Bad connection?
if you are on mobile maybe the game doesn’t support your device?
