SUMMARY
Writing GPS data into photo's Metadata does not work.

STEPS TO REPRODUCE
1. Using "Tools > Edit Geolocation" to set geo location of a picture. Closing the tool after clicking "Apply".
2. "Item > Write Metadata to File"
3. "Item > Reread Metadata From File". 

OBSERVED RESULT
1) After writing Metadata to File Longitude entry is missing in EXIF Data in "ExifTool"
2) Geodata icon of image is deleted.

EXPECTED RESULT
1) All Geodata should appear in "ExifTool"
2) Geodata should remain in picture after reading it from the file again as it should have been written before into the file's Metadata.

ASSUMPTION
digiKam does not succeed to write the Geo data correctly into the file's EXIF Metadata.

SOFTWARE/OS VERSIONS
Windows: 10 Version 22H2
macOS: 
(available in the Info Center app, or by running `kinfo` in a terminal window)
Linux/KDE Plasma: 
KDE Plasma Version: 
KDE Frameworks Version: 6.10.0
Qt Version: 6.8.1

ADDITIONAL INFORMATION
All operations had been done on a Windows laptop in an admin user account. The files storage folder was initially a NAS shared folder. However, the same behaviour was confirmed using the local folders on the laptop.

IMPORTANCE
Without the ability to write Geolocation into the files EXIF data, that information will be lost when
- sharing images with others
- migrating to new devises
- using other image viewing applications.
