I’m having the same issue as @socke, I guess. I have created a group assignment with student teams of 2 people. Students have started creating their teams and keep doing so, but when looking at the submissions, I keep seeing 20 teams and 20 students not on a team. There’s pagination for two pages, but no matter which one I click on, I only keep seeing the first 20 teams.
When students create a new team that is among the first 20 in terms of sorting, it will show up. Otherwise, I have to switch to the organization to see all of the teams, that is a bit unhandy.
Please contact me if you need to look at the classroom and/or the assignment, I’d love to get this working again. It might be a group-assignment thing, as @socke has already stated. It’s most likely not related to the browser. The behavior is the same for all Blink (Chrome, Opera, Edge) browsers, and Firefox.
