Hello
I upgrade to 9.0, and noticed that when using the GPS and settings the update freq to start(1000,0) the events fired as if I used start(0,0). I have to have the app ready for tomorrow, so I downgraded to 8.8 and the events seem to fire correctly. I don't have time to futher investigate this, so maybe other can check it.
I think there might be an issue to background services in 9.0 as the app is being killed even though the necessary settings are applied to the device(s) to allow the app consume battery. I will need to further investigate this when I have time.
Regards
John.
