When you save a photo from WhatsApp and add it to PYM, the location shows as unknown. This happens because WhatsApp removes the hidden location data from photos when you share them. There is nothing wrong with PYM, it simply has nothing to read.
What is EXIF data?
Every photo your phone takes stores more than just the image. Alongside the picture itself, your phone quietly saves a set of details called EXIF data: when the photo was taken, what camera settings were used, and where you were when you took it.
PYM uses that location information to show your photos on the map and connect them to the places they belong to.
What WhatsApp does to your photos
As part of sending photos, WhatsApp removes the EXIF data, including the GPS location. This is a deliberate step, not a side effect. The photo looks exactly the same, but the hidden location information is gone.
Because PYM reads location from EXIF data, a photo saved from WhatsApp simply has nothing to read. There is no location to show.
What to do instead
Use the original photo from your camera roll.
If you took the photo yourself, you will find the original version in your camera roll or gallery. That photo still has the full EXIF data intact, including where it was taken. Adding that version to PYM will show the location correctly.
If someone sent you the photo via WhatsApp and you want it to show a location in PYM, ask them to share the original file instead. Options like AirDrop, Google Drive, or email send the file as-is, without reprocessing it, so the location data and other information stays intact.
Your original photos always carry the most detail. When location matters, go straight to your camera roll.
