Hello,

I'm part of the ONLYOFFICE team that develops the ONLYOFFICE Docs integration for Box (https://app.box.com/integrations/onlyoffice_personal/i). Unfortunately, we’ve ran into an issue that prevents us from signing in to our account. We have lost access to the phone number that had been used for two-factor authentication and the attempt to change it has failed: we used the correct account backup code to log in and change the 2FA number, but any subsequent login attempt somehow continues to require a code from the old phone number and the backup code no longer works.

We have been unable to contact your support team since we have no way of signing in. I’ve also attempted to reach out to sales@box.com but never got an answer. Is there a chance that someone from the support team can help us with this?
