Seems to be the DM view count in notifications is a mini bug
When I close and reopen, +1. Close and reopen +1 (fyi nostr friend nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z). We probably don't need view count on DM notifications too I'm thinking cuz encypted DMs and all, it's always 2 views. Probably known, if so just ranting then
