What you were expecting to happen, and what actually happened
I was trying to access Guild Wars or Guild, but keep getting one of these (apparently random?) errors, which then gets stuck in a Retry loop until I force quit and restart the game. Other things (such as Games, Adventure Board, Journey) load fine.

How often does this happen? When did it begin happening?
It started with the day (Thursday, 18 March 2021) and has continued throughout.

Steps to make it happen again
As above, trying to access Guild Wars or Guild.

I have this same issue using an android device. at least 3 other Guildmates have this same issue.
