I am subscribed to my Favorite Tags for delivery every 15 minutes. I have not received any emails from that filter in 14 hours, although looking at the filter at StackExchange shows plenty of new questions. I continue to receive emails from other sources, so it's not a general failure of my email.
Is anybody else experiencing this?
Also, when I view the filter at StackExchange, there's an "edit" link that should let me change whether and how often I get emailed, but it does nothing. (Tried Firefox 11.0 and Safari 5.15.) I intended to toggle the frequency to see if that jump-started delivery.
