Gear Manager won't detect my gear s2, even though bluetooth can connect to it just fine

[Davy Ling]

So I purchased a refurbished Samsung Gear S2.

Everything about it works, except that the Samsung Gear Manager can't discover it. I don't know why, because regular bluetooth can see it and connect to it just fine. The manager can't even discover it when it's connected to my phone via bluetooth. I don't know if this was a refurbishing error or a phone error - or something else. I tested this on an iPhone 7 and an HTC Desire 510. None works.

If someone could please help me, I would be very grateful!
