Groups do not show on multisite except in search builder
Ever since Civi 5.35.2, group search field does not populate for non-admin users. It either has no dropdown options or is entirely missing. No groups showing under 'Manage Groups'. See discussion here: https://github.com/civicrm/civicrm-core/pull/19372. Before all groups would show. On multisite. Users have
CiviCRM Multisite: list all groups in domain permission. Groups do show in search builder but outputs the ID of group and not the name.
I've ruled out extensions (renamed directory) and the WP plugins. Replicated on another multisite as well.
A non-admin user is able to see groups on domain ID 1 but not on any other domain. That is as far as I have debugged.
