As a CiviCRM admin, I have no problem saving field mappings for export, but it isn't working properly for non-admins. I can't see any permissions that might be missing (I don't want to give them full admin permissions). The problem showed up with exporting participants, but the problem is also there for contacts. All works fine up to the actual save but it then hangs with a spinning wheel on the final save button. I thought it might be the same as What permission set allows a user to be able to save a field mapping? but the symptons are different there in that they cannot see the save option at all.
Using CiviCRM 5.35.1 on WordPress.
