@Laura L. Agostini - Yes. (That was easy - thanks!)

I am currently signed into three browsers on two computers, the Miro desktop app on two computers, and the mobile app on my Android device.

Ok.  that helps narrow it down.  I can’t seem to log in on a PC laptop with my work Microsoft account even though I am currently logged in with my MacBook.      It keeps bouncing me back to the work or personal account choice box.   I can access it via the web though.  I don’t know if I will ever understand the mysteries of Microsoft.

Perhaps your work has a Business or Enterprise Miro plan? If so, they may have SSO/policies configured which are causing the behaviour you are experiencing.

that’s possible - I will look into it.  I was actually surprised that the app downloaded without the admin   sign on but I then didn’t see it in our district collection.  I will look again - things change rapidly these days!  

I could be that I used my district email but a custom password - I forgot about that possibility.

Thank you!
