See https://forum.inaturalist.org/t/photos-metadata-exif-lost-with-the-inaturalist-application/57805 I can replicate with 1.35.5 (619)

1. Make sure that a photo saved to your device has location info, etc.
2. Share to iNat, or import from within the app. Upload the observation.
3. On the website, check out the photo's page.
4. Basically no EXIF data remains.
