Phone... LG V10, Android marshmallow 6.0
Pairing in app fails at about 60%. If I pair through the phone the device will show up in the app but then it won't sync. Been able to get it to pair in the app by completely resetting the device back to factory pairing mode then pairing, but even then it will fail on sync. I have tried every combination of pairing, resetting, reinstalling etc.
I downloaded connect on my friends iPhone and it paired and synced instantly with no problems so it's not the device itself.
