App not working

iOS: 9.3.1
iPhone: 6s Plus
Zeroner App: v2.82(2820)
Firmware: v2.0.1.6
Hardware: Iwown i5 plus

The settings within the app will not change and so I can not change the settings of the wristband. 24hr vs AM/PM clock, metric vs English etc... Also data from wristband is not syncing back to the app. I can receive text messages, caller id, and the time from the phone pushes to the band, but not able to push any settings to the band such as AM/PM style display instead of 24h military style display, unit metric vs imperial, etc... I have tried many many times all suggested methods of re pairing to the phone without success.
