I’ve recently created an education account and I’ve been successful in adding “most” of my students to the team. There are a few, however, that I’ve added, but they are being prompted for credit card info when they try to register. I see 409 errors in the dev console that I didn’t see when I registered other users.
These were some of the first users I tried to add and I was trying to add a bunch quickly, so that may be part of the issue. I’ve included an image.
