After reading a couple of old threads on this topic here in the Technical Help, could you check your junk folder and see if any notifications bounced back as undeliverable to me?
I am watching a couple of threads, haven’t received any notifications for the past few days, and the threads have been quite active.
I should clarify that when I say I am not receiving notifications, they are the ones that are forwarded to my email.
It is most likely not a problem on COTH’s end as I am also having a problem with my Outlook email account. Just wanted to be sure things are okay here before I talk to email support tomorrow.
