I've recompiled in release mode and it is now working. Could be an intermittent bug or only in debug. Will provide more feedback as I test.

Done some testing at the weekend. The background timer stops working if I call react-native-push-notification or react-native-tts in the background function. I spoke too soon. Yesterday app was running fine...

Further testing shows that it doesn't consistently work even with a new project and only this module. No updates on this module since the beginning of August so I guess...
