I have added some additional logging information that should be available in the next build.
Please enable it once you install it and let me know what you get when you start TrackMe.
Thanks _LEM_, I'll try the logging to a file when it's available.
The phone I use is the Xaomi Redmi 2
It has it's own rom based on Android 4.4.4 running MIUI 7 (the latest version of this).
The ROM is updated regularly - and it may be that an update t the rom coincided with your Trackme update and that may be where the error crept in (although the error seems to be with the connection to google play to confirm that it should be ad free??)
I have been able to the issue with the emulator. It's very weird.
Based on what I found on the internet, it seems to be a bug that affects some devices. I found a workaround and I will be testing it for the next few days before
being sure everything works the same way.
Thanks for your feedback.
