Unable to sign in via Microsoft

[Suvinda Rupasinghe]

I usually sign in to Trello via my company email address, which uses a Microsoft 365-hosted domain. Yesterday there was a problem with my M365 account and my password & 2FA/MFA information had to be reset.

Since then, when I sign into my Trello account using my usual M365 email address and password, I don't see any of the Boards I used to be a member of. 

How do I get back access to these Boards? Our company Trello admin tells me that I'm still listed as being signed into these Boards.
