Band 2 not fully compatible with Lumia 635 ?

[Windows Central Question]

When using the Band 2 I cannot receive any messages on the device, although it has Windows 8.1 Update installed and Bleutooth 4.0 (the requirements as listed bij MS).
Which Lumia models are fully compatible ???

What messages? The band is compatible with any Lumia (Android and iPhone as well)

If you mean that you're not receiving notifications, it's a known issue which pops up from time to time. Check if Bluetooth isn't turning off for some reason/ if you're not too far away from the device (BT range) and finally ha reset might be in order (no guarantees)
