Good afternoon, we updated from Moodle 3.1 to 3.5 recently and are getting used to the new enrolled users list format (/user/index.php?&id=1340), but can't figure out how to do something that was very useful previously. This is filtering by "not in any group". I can filter by specific groups, but can't seem to easily list users that are not in any group.
There is an existing issue for adding this filter again: https://tracker.moodle.org/browse/MDL-61967
For now, while it gets fixed and you're able to upgrade your Moodle version, you can go to the Groups section and access to the "Overview" tab. There you'll see the users who don't belong to any group:
Thank you Sara! I'll watch the tracker item and vote for it and thank you for the tip about it also being available in the Groups -> Overview
