i suspect this issue might even go deeper: not only does the character count not change, but if you tap your profile pic a second time to switch back to the original account, it won't show it in the menu!

it looks like that menu, in general, doesn't show the current account (which is ok), but then when you use it to switch, the (now-hidden) contents of that menu don't get updated to reflect that the current account has changed
