Can't coop

[crystal kindle]

I can't invite people to coop, at least in tower raid, I don't know what happened

Restart game maybe?

You cant play on quick resume because the game doesnt like it

and if your internet shuts off and shuts back on really quickly, it also causes that same issue

What floor were you on in tower raid (if your near the end, you cant invite people)
