Anyway. This ist the reply from pebble:
"Thank you for letting us know--I'm happy to help!
This issue can often be solved by toggling Airplane mode on, then off on your phone. If this doesn't help, please use the steps below to correct the issue.
- On your phone, open Bluetooth settings and find any devices labeled 'Pebble'. Tap the gear icon, and forget the devices.
- If possible, open your watch's Settings, and open Bluetooth, then select and forget your phone. If the menu's unavailable, simply hold the down button for 10 seconds.
- On the watch, press and hold the left button and right middle button simultaneously until "pebble" appears.
- Re-open the Pebble app and follow the instructions to re-connect your watch.
Instructions for setting up your Android notifications can be found here:
Let us know if the issue persists after completing these steps, and we'll continue to troubleshoot with you.
I will try this later.
