Not able to log in to Microsoft Teams meeting.

I had a link sent from an SFASU faculty member for a meeting via Teams.  At first, it would not let me in.  When I was finally able to get in, It did not show me on the screen, but I could see the person I was to meet with.  She could here me.  Then, it all disappeared.  I tried a couple more times, but it did not work.  It told me to try again.  So finally, we just met via Zoom so that she could share her screen and talked via our phones.  I have had issues in the past with this happening on Zoom meetings.  But, that was fixed by Chase--which I really appreciated!  Not sure why it is happening now through Teams.
