We are using a custom permission scheme, and Groups to separate user access by client. We had to remove the Browse users and groups global permission, as users where able to see other users, and in there Worked On list were able to see issues (summary only - click through said no access to issue - as desired).
However, the @mention functionality ceased to work for the users without this global permission.
Is there some way to configure via custom Project Roles or Teams or something so that we can still @mention people on the same project, but not see users and Issue Summaries from other client projects? I thought perhaps the Browse project role should be made as a Browse per Project role, but not sure it this is the right direction to go.
Any help would be appreciated:)
