To the developers: this is broken because your Android app is targeting Oreo but does not support notification channels, so all notifications are getting suppressed on that platform level. You have two options to fix this:
- Target a lower platform level (this won't stop your app from working on Oreo unless you set a maxSdk)
- Add notification channels and keep the app targeting O: https://developer.an...#ManageChannels
As it is, it's a pretty bad situation right now. Moreover, you also need to ask for the required permissions when the app starts instead of expecting people to add them in the settings. There may not be a lot of people using Oreo right now, but the problem will only get worse with time and it'll hurt your app's ratings/purchases.
- Friendly Android dev :-)
