There is no "Pebble specific enhancement" in AquaMail.
There is Android Wear enhancement, and it's enabled when my code detects Pebble's app -- because Pebble says that their software can handle notifications enhanced for Android Wear.
And those Android Wear enhancements are "riding on" standard status bar notifications, that's how Wear works.
If you're seeing duplicates on the Pebble, it must mean that:
- Pebble's software is mirroring the status bar notification, the "basic" part
- And then it's mirroring the Android Wear enhancement.
Pebble's software. Not AquaMail.
Please talk to Pebble support.
