Our district has assigned classes to various teachers throughout the district. This teacher in particular does not see any classroom Teams displayed on her Teams list. I've scrolled to the bottom of the Teams list, there is a small cog(or gear) visible. This displays a "Manage Teams" option and she is able to see her class on the list. It just seems like her classes are being held in a lobby, and has no access to it. In the image you can see only 3 Teams are available on her Teams list, but she is part of 4 Teams, they are listed as active and she is also listed as the owner.
We have tried troubleshooting this issue in various way. We have talked to our Admin who is charge of Office for our district with no luck.
