Looks like mine is working now. It did a weird thing though.
1. I enabled PLP and saved it.
2. I viewed PLP
3. I clicked on "edit profile" on the PLP to change my avatar back
4. I saved the regular avatar
5. I noticed the link to the PLP on the profile edit page was no longer active. The checkbox to enable PLP was unchecked and greyed out.
6. I tried returning to the original edit profile page with the browser back arrow
