I have a slightly different problem - pm notifications arrive about 24hrs after they were written on the forum. I have usually read them by then anyway.
I’m getting a delay in email notifications, although it isn’t as much as 24 hours, but can be a few hours. As I’ve usually logged on again in the meantime, it makes them a bit redundant!
Yeah, I am finding the same thing, emall notifications arriving days late. My tapatalk notifications are pretty quick so I can generally compare the lag that way. Then this morning I got a whole lot of email notifications at once that were really old so must be lag in the email system somewhere.
