Hi Kudpung, you mentioned that your notifications are stuck at 99+. This should now be easy to clear, from the Special:Notifications page. Click the "cog" icon in the upper corner, and there should be a link to "Mark all as read in selected wiki". (screenshot). If you don't see this, or if it doesn't work, then please let me know what browser/OS you are using.
