Same problem.   Tried turning Bluetooth off/on..  Mobile/ international data (I'm traveling overseas).  Power saver off/on.  Restart phone.  Restart app.  Reset tracker.   Message says "tracker not found".

Same problem here. Has anyone found a solution?

I have same problem. Syncs then says tracker not found and all displays go blank. It is definitely the app as problem much worse since new dashboard.

I am having the same issue with my flex.  Not syncing and not finding the device. Its been working fine until the latest update.
