Just an FYI to anyone else with a similar issue hoping to get this fixed, I have not received a single email notification in 17 months. This issue has never been remedied.
If any of you figure out a fix, I'd sure love to hear about it.
In the past few weeks, I have stopped getting email notifications. They have been quirky since the change to the new boards but I was still getting them. Now nothing.
Update for everyone here. Thanks to @SteveH I finally have a decent workaround. Try changing the email address attached to your account. Then have the emails from that account forwarded to your preferred email account. It worked for me. I hope it works for others.
