For about a day or so, I haven't received notifications. When I click the bell in my menu bar I keep seeing "Enable push notifications?" even though my site is already listed as enabled to send notifications in Chrome settings. Clicking the "Enable push notifications" button does not help: the button says "Enabled", the message keeps coming back when I click the bell again.
Edit I was able to enable the notifications, got notifications for a few hours, then this pops up again and I can see in my notification settings (mydomain.com/notifications/options/) that my notifications are no longer enabled.
