When I make a report (under appropriate circumstances obiously), the menu does not go away upon submission but a notification says it has been submitted while the menu with the options and comment remains.
which menu specifically are you referring to? Can you send a screenshot (for example, before you send it?) - I just tried on my end (the two report panels I can think of), and could not replicate the issue (at least, not yet).
(contents blurred out for confidentiality and this was not sent)
This screen is the little yellow report flag button menu
Hypethotically, when I hit the submit button after writing comments and choosing a reason, it says that it has been submitted but the same screen remains as if I never pressed the button.
Edit: If a unredacted version needs to be sent, I can try to do a DM or send via help button
