Hi @Olivier Beltrami ,
Sorry to hear about the trouble. Could you please confirm if your colleagues in Italy are on the public releases or beta releases? The reason I am asking this question is that, recently, we rolled out the new update of the InDesign public version, which is being done in phases, and Italy was among the regions in which the update was rolled out in that phase. Possibly the auto-update on their CC was on, and it auto-updated. If you're not seeing an update on your end, please bear with us the update will be available in your region soon.
If your colleagues were on the Beta release, please share your colleagues, Adobe ID, phone number, & a suitable time to get in touch through DM by clicking on my name.
Regards
Rishabh
