I got around to digging into this a little today, but am unable to reproduce the mentioned behavior. I attempted three messaging scenarios using the settings mention (PMs enabled and TL2 can invite up to 10 times a day):
- Admin → TL2
- TL2 → Admin
- TL2 → TL2
I tried to see if subsequent replies would break the ability to add new users, but interestingly all of the above scenarios showed me an “Add” option for both the owner and participant. If anything, I feel like it’s a little too lax right now.
The only time I could get a “Remove” button with no “Add” option was when I was a TL1 participant of a PM someone else had started. I was able to remove myself, but could not add or remove others.
@sdpiowa @diakopter are you still seeing this issue? If so, can you see if you can nail down some detailed reproduction steps for me to try out?
