Same issue here. Logged in on the Teams app to the correct account, logged in through web browser to the correct account, creating a meeting in Outlook using this account, and using the Teams meeting add-in on Outlook for meeting invites.
Even with all of these steps taken it still gives me a Teams meeting hosted by a separate account through my consulting firm and I'm forced to switch accounts in Teams in order to open the meeting and submit attendees. Microsoft just doing Microsoft things once again.
