That's also what happened to me. And I had to sign in my account multiple times only for it to say that both email and password are wrong. I also can't access my bookmark. But after a few hours I tried logging in and both my bookmarks and history are back. Maybe wait for a while... (though I assume it's back now?)

My history list wiped out??? What happened? I always checked my history because it has faster updates but what the heck is happening? I refreshed and it's still blank
