Hello @didier.varin52x8m
Thank you for sharing more information.
I tried to replicate the issue by testing these blocks with an iPhone with iOS 18 but I could see the latitude and longitude.
Did you use the Thunkable live app?
Have you checked that it has all the permissions to true?
Tracking permission is needed!
