20 bytes truncation bug in BLE stack of Edge devices - please fix this soon!

For Garmin Edge devices, we see several bug reports on

1. BLE GATT server messages truncated to 20 bytes

2. incomplete scan records for BLE advertising messages > 20 bytes

The root cause of these issues may reside on LL2CAP or even physical Link Layer, resulting in a non fully compliant working (G)ATT layer.
If this results as the truth, the current BLE stack of Edge devices never can have passed a BLE compliance test.

Thus, the affected Garmin devices wouldn't be compliant with Bluetooth SIG's requirements.

Please fix this soon! ETA?
