After a few hours of tinkering, some insights on the new map (2019.12).

The Primo 2.4 software on the WINce operating system works properly with the new map (2019.12).

Primo NextGen for Android works properly with the new map (2019.12).

The iGO8 software that works on the WINce operating system does not work with the new map. Back to the previous map (2019.07), and the software works properly.

I wonder what in the map can't fit the iGO8 software, even though the type of map remains the same, with the fbl extension.
