Facebook notification issue
Something seems odd with the Facebook notifications in macOS Sierra. I suddenly had an issue that whenever there is a notification in Facebook and my Mac notifies me about it, the notification banner on the upper-right hand corner of the screen says that I have 200+ (about 278) notifications pending. Also, Notification Center displays 200+ notifications.
I checked the notification in Facebook and I only had 1 notification, not 200+ as displayed by the banner and in Notification Center. It is as if that 1 notification in Facebook is multiplied by more than a hundred-fold in Notification Center.
I tried deleting my Facebook account (via the Internet Accounts tab in System Preferences) and creating it again, but to no avail. For now, I just unticked the Notification check box under Facebook's Internet Accounts settings to stop the notifications.
I hope that there's someone that could help me with this issue. Thanks in advance.
