Correct. I was just not seeing the email notifications under the default settings.
I would like to see a fix here. A current workaround is Admin > Customize > Text Content
to modifiy the text for js.groups.request_membership_pm.body
to remove the @mention and replace it with a link:
I would like to apply for membership.
https://example.com/groups/{{groupName}}
I could not sort out how to pass the {{base_Url}} variable for the site (so you must insert your URL here).
I also could not insert {{group}} or {{group_name}} variables for the Group Title in the PM.
I think the preferred approach would be to just include a sentence with a link using the Group Title.
I would like to apply for membership in <Group Title>.
The workaround above doesn’t solve the issue on removing the requirement for “Everyone can Message/Mention.” Hopefully that requirement will be dropped.
