@cdcme re: merge conflicts, I don't know the best way to resolve them with git

Here's the FE choices:

1. This tooltip thing needs to be reworked after this is merged, so for now accept the code on main knowing that it's undoing my "if this is mobile, show the tooltip onClick" work and I can do a followup PR as an unreleased bug for that part of the feature due to this conflict

2. This branch just needs the || enrolUrlError added to it

3. Accept the code on main
