Thanks for the quick reply. Unfortunately, I couldn't open the file you sent me.
In the meanwhile, I think I discovered what's happening, so I'll share that:
when checking the UL as described, I didn't have installed all the plugins that were included on the saved .ini file.
The moment I deleted from the Settings the plugins that were not actually present on the device, UL loaded normally and allowed also the other plugins to load if checked
(previously, although UL was unchecked and Calendar was checked, Calendar did not appear on the screen, unless soft reset - and the story repeated after activate-deactivate UL).
It seems that UL is kind of "all or nothing"
