I'm having massive issues trying to access my web wallet, and the login for it is beyond stupid, anyway. You have to enter a username/password and pass the infernal (and totally useless, because hacked) reCaptcha just to then have to go through reCaptcha again to enter a 6 digit Google 2FA code. Why not ditch the reCaptcha which everyone hates and just use a password and 2FA?
Anyway, it seems the devs know there is some issue with accessing the web wallet and one is encouraged to send them an email about it. See the below reddit post for more details:
