Are you getting "notifications" on your phone that says you have X number of messages ... or are you talking about the "Notifications" link at the top of this page banner ??
If it's the phone app and you've answered all the PM's by computer .... just swipe that notification off and don't worry about it.
If it's the Notifications link at the top of the page, or you haven't answered all the PM's ... then you will need Slab's help, or possibly "G" can figure it out.
(Oh yeah, I moved it here from the Test Forum, so it would get more attention )
Slab may be on the road already, and may not have service or he's driving .... "G" is likely busy and will pop in and out during the day, so he might catch sight of this thread and respond, later. Just hang tight and we'll get it figured out & fixed for you !!
