Expo notifications dont arrive on android device

Please provide the following:

  1. SDK Version: 42
  2. Platforms(Android/iOS/web/all): Android
  3. Add the appropriate “Tag” based on what Expo library you have a question on.

I have some notifications that don’t arrive on android devices. I am sending the notification to 1k users with the expo node sdk in chunks at once without waiting between chunk and chunk. I have some provider providerError and devicesNotRegistered but its seems that isnt the problem. I set priority to Max in my app (Notifications.AndroidImportance.MAX) in the default channel but i dont specify the channel when sending the notification.

I have no idea how to discover where is the problem.

i’m experiencing the same thing, device A receives notification sometime, sometimes it takes 20 minutes sometimes device b doesn’t receive at all ,sometimes device b receives and device A dont, this is so hard to debug because it’s so random
