I want to report a bug since 17 Nov, using Mobile version, this number of unread notifications won't disappear even after we opened or read it. So if I use mobile version only all the time, the number keep increasing by the time, even after we opened it. But if we opened it in Full mode (Desktop version) it is normal (number disappear soon after we read it). Not a big problem, just to let you know. Also it might something to do with the update mentioned earlier as it happened at the same moment after 16 Nov. Maybe somebody could revert or check it back. Thanks.
