Hi
If its any consolation I have had a similar problem. Not sure yet if its the way I set it up.
Something fundamental is not clear to me. When I go into Assignments on my Teams channel then choose Quiz and create a form it does not appear as an assessment when i share it. in fact i can't see where it exists at all at the moment.
Do I need to add it as a assessment and add the link. Will the responses come through into assessments? Do I need to add a post? I did this on Friday and the one student who has responded has no responses visible.
Lots of things I don't quite get.
Have watched a lot of the training videos.
