Issues applying available updates for IQ datafields

Since an undetermined moment, I am facing lot of issues related to updates of IQ datafields.

New updates are shown as available by GCM, but there's no way they are applied.

Even today, one datafield, that was finally updated yesterday, has reverted to previous version later.

Removing and installing again seems to work.

The issue is happening with multiple datafields, mine and from others, and for several users.

Uploading of datafields to Connect IQ store has not reported any issue in case of mine.

In my case I'm using:

- Edge 1030 (13.26)

- Garmin Connect Mobile for Android 4.51.1

Is anyone dealing with these issues? Is there any known issue related to Connect IQ store?
