Notifications bug – Trello: organize anything! Review

I love the app but for some reason it never syncs the notifications properly. I go through all the boards, marked all notifications as read, and yet I still see a glaring number at the top right corner of the app. I have no idea how to remove it and it’s been weeks since it’s been there. Even the recent update to the app hasn’t fixed it.
