Extreme lag or delay after update

Cannot use my guild bank, send mail, or move anything in bags.
Not sure it is related to low level character or in general.

Even trying to log out or exit the game it does not work.
Nothing is responding…

Opened issue on general support but I am playing on mac.
Disabled all add-ons and issue still persists.
Other characters working better although the guild bank does not work.
This level 10 character is totally unplayable.

Update: Tested again… Everything is working Ok now except for the guild bank.
