Q: When we switched to the new format in early January, I had no problem navigating, up-dating my profile, checking my subscriptions, etc. Email notifications of new posts to the threads I subscribed to were coming very regularly. Then on Sunday Jan. 22nd. "all" email notifications regarding subscription updates & PM's stopped. Please advise.
A: We are aware that some are having this problem.
Other than doing the things here
you can try unsubscribing and resubscribing and re-doing notifications settings to see if that kick starts the system for you.
