Hi @mnhq
I posted about this recently. It's still happening.
The app never showed the deletion message for threads I'm On (or Watching). The thread just disappeared.
However, if I wanted I could go to the mobile browser version & check there - not any longer. Deleted threads gone there too.
Yesterday I went on the website on my laptop & checked there - nope, gone there too.
The thread today was AIBU to wake DH. I had reported it as I was concerned for OP. I assume it's been deleted but it's just vanished for me.
Can you take a further look?
