CIQ widgets cannot be installed on Edge 1040

With Garmin Connect IQ Store (tested with version 2.16.0 Android and iOS) it is not possible to install applications of type "Device App" from the store that were created from a widget (using type="widget" in manifest.xml). In the Edge 1040 simulator CIQ apps of type "widget" work fine, but when published on the Connect Store, they cannot be installed. Even sideloading widget applications built for Edge 1040 do not work, they don't appear neither as a glance or as a widget (by swiping down).

I tested on Edge 1040 Solar with firmware version 12.15

How to reproduce:
1. Open Garmin Connect IQ Store
2. Select Edge 1040 as the device
3. Find any of the below applications:
- AccuWeather MinuteCast: https://apps.garmin.com/en-US/apps/c1facb1f-db5a-4352-adf3-9dd09e6fc668 
- Bike Lights Control: https://apps.garmin.com/en-US/apps/fa3c2332-76e3-4ba1-8528-32a0fd617ab1 
4. Tap on the "Install" button

Expected behavior:
After tapping on the "Install" button the application should be installed and the "Uninstall" and "Settings" buttons should appear.

Actual behavior:
After tapping on the "Install" button, the installation fails and the "Install" button is appeared again.
