Need some more information. What platform is this on? Desktop, mobile, embed?
I’m also not clear on what you’re talking about on any of these but the platform might clarify a bit.
Mobile. When I look at the phone screen and I see 1 notification (red bubble) and I click it, no user shows up. The location where the user who sent me a message should be is empty.
While remaining on the same screen (the empty screen with no user) the red notification number in the bottom begins to increase up (not because I"m getting more notifications). Sometimes it goes up from 1 to 9, from 9 to 33, from 33 to 101 from 101 to 202 and so on (that are just random numbers). But when I browse to a different page it goes back to showing 1 notification.
