A quick search of the forums shows that people have been complaining about this for over a week. Not only does it affect multiple aspects of the game, as Sannik explained, but it ALSO affects EU servers (there are threads about it over there).
There is no UI or addon element that’s going to cause these kinds of problems. Full stop. And it’s no coincidence that the majority of people complaining about this issue almost all recently performed some kind of major character service like a server transfer.
It doesn’t require first-tier troubleshooting, and these autoreplies aren’t even troubleshooting anyhow since the situation is very obviously not related at all.
Some GMs are helping, and others are pretending it doesn’t even exist or handing out pointless auto-replies. Every time someone like you shows up and tries to defend these policies and responses, you just make it all worse.
