I have found an issue,
If I add new group, and add group members or node to this group, as you can see on screenshot one time i have administration theme(Seven), but if I go to members tab or nodes i got loaded another theme. Testing as a admin.
I see that this two tabs(nodes and members) are in Views with paths /group/%group/nodes and /group/%group/members, so is there any quick fix to use only one theme in whole group?

It's likely this issue predates Contrib.social: some issue and comment data are missing.
New option for Views page displays to use the admin theme ✨ New option for Views page displays to use the admin theme Fixed was merged to 10.1.x back in 2023.
I've added the config change to the module view against 3.3.x
Please note, if you've already exported the config locally you may need to make the same change to you config manually.
