Hello,
I don’t know this is maybe a bug. Before, I can added myself to personal chat and I can make notes to myself. Now It is not working. I leaved from my personal chat and i can’t re add myself. I think this happen since the personal chat leave feature.
Edit: It seems to only happen with admin account.
Thanks 
Again I don’t think we should be accepting public bug reports on chat at this time @sam
Update: It works for me now with admin account too. Thanks for the fix.
Yes this certainly was a bug that we got fixed. I think if a regression like this popped up again we would be happy for a meta bug topic. Got to keep this working!
