Hello @AliciaSwackhame 

I wanted to update you with some new findings and apologies for getting this incorrect as this behavior has been updated!

When a Group is created via the Credentials LTI, name or email changes made to the course roster are synced automatically. When a user's email address is changed, badges awarded to the previous email address are revoked and re-issued to the new email address.

Please see our release notes regarding this update:

Please disregard my previous comment about needing to delete and recreate groups, as this new Roster Sync function has been added to groups as of December 2023.

Hope this helps!
