Yes, me too. when you sign in. it pops up a screen saying configuring browser or somethng like that then puts you back to sign in again for a 2nd time.
The other day it said I had too many attempts and had a time out, when I had only done it once or twice.

Something I've noticed is that the emoji page has put itself on my desktop permently, in fact several, one after another pop up, then magically disappear from sight. This happens every time I power up my laptop now (before turning on internet) so I know it's saved itself to my computer even though the emoji window disappears from desktop view. I can't remove them because the emoji window disappears from sight within seconds of popping up. I've been worried it might have a virus in it but idk.
