I got them, so looks like it does work as expected, my instance admin must just also get my reports. Kinda weird but if they go to the right place as well I'm not too concerned.
Edit: strikethrough is working on my end in the connect app.
From reports from users on another instance? I guess I'm just concerned because when I report content on another instance my admin account gets a report notification on my instance. Obviously I can't do anything about content on other instances so I just want to make sure the right people are also getting my reports.
Edit: ok another user just tried it on one of my posts, it looks like it works as expected, I just also get my own reports sent to my admin.
