I recently updated my Android app to have push notifications.
When I tried to send a push notification I get this error message.
"There were no devices associated with your app ID. The notification was not sent."
Does this mean that currently no-one has the latest version of my app or has downloaded the latest version that now has push notifications. or is this a bigger problem?
Yes, it means that devices have not been updated with the newer version or that the devices with updates have not yet been registered. It can take a few hours.
I just tested and it works well. I think the best would be for you to test by installing the APK on your device and you'll have a couple of things to check:
- Once the App is installed, go to the menu > settings and make sure Allow Push Notifications is checked (it should be by default.
- Also go to Settings > Device > Sounds and Notifications and make sure you Show All Content on Lock screen
