We're having the same issue with our Mac App. Everything was working fine with push notifications coming as expected but all of a sudden users are reporting delays or not receiving at all.
Timeframe: Ongoing, Exact start time is unknown, first report was 2023-11-30T03:45:00+13:00
Observed behavior: On Mac devices, after sending a push notification, nothing is received in the app. After waiting for several minutes, we turn off the wifi on the mac device and turn it back on, after connecting to the wifi again the push message is received. Very rarely push notifications do come through promptly as expected but this normally only happens once or twice, then the following notifications are delayed. The delays observed are between 5 minutes and 25 minutes.
If we try and use the Push Notifications Console we get this:
If use try once, it logs "discarded as device was offline"
If use an expiry instead I get "stored for device power considerations"
Once I toggle my wifi connection the push notification comes immediately and I get the log "successfully delivered to the target device"
Business impact involves users not receiving any type of push messages. We use push messages which may include imminent threat to life alerts that show fullscreen on the users Mac device. Without push notifications mac users will not receive these potentially imminent threat to life alerts.
