In game chat spinner spins forever on cellular

I’ve been playing this game on my iPhone 6 with no issues until 1.12.7 build 395. Now, my in-game chat only works over wifi.it just hangs there with the spinner with cellular and no wifi. Is this a known regression? I’m also on iOS 11.4.

There is another thread about this. Do you have T Mobile? That seems to be a common theme. I’ll necro that thread because I have some new info.

Thanks Oblivion. No I’m in Canada on the Rogers network. Maybe it is this IPv6 thing but it was all working until the update.
