Hi @maurizio.consilvio, thank you for your message and sorry for the issue you got
In regards to the Google error that appears on the map it is most probably because you have (1) signed up for a trial account, but have not converted it to a paid account or the second reason is that you (2) have not linked the billing account to the project yet. Please make sure to check the above point and see if that makes any difference.
In order to better understand your use case please share a link to your Bubble editor and let me know the steps (details) that will help reproduce the issue.
Waiting for your reply!
Have a good day
