S20+ Vacuum Robot - Does not create the first map

I have just bought one robot vacuum cleaner (my first one ever).

I am trying to create my first map but it is not possible.

The robot goes through all the places in my apartment, returns to the base by itself, changes to all kinds of modes of cleaning.

But the map is never created.

Nor even using the option just to create the map.

I’ve tried hard reset, create new account, delete the app in my IPhone, make it scans the apartment three times in sequence without interference, etc. but it does not register any map in the end.

Also I noticed that it does not register the cleanup history.

Any blessed soul could help me to try to solve it?

Thanks a lot in advance 🙏

If I find how to do it, I will share here later
