one thing I would try doing is clearing your cache/cookies just for the relume site and try logging in again. You can easily do this near the address bar - I believe the same is true for Brave but its been awhile since I have used that.
this error is no longer wide-spread, so I am trying to rule out what might be unique with you - and maybe some sort of connection to a cookie got corrupted during the down time.
Sounds good Richard, thank you for your patience in trying to help me troubleshoot this with you - I hope we can resolve it for you soon and apologies for the issues.
especially during times of connection issues - we store a lot of data in cookies actually - non-sensitive data - like a prompt or a status of a sitemap etc.
