Photo thumbnails are sometimes not generated.
Not processed
When I take a photo with geotagging, it appears as a thumbnail on the map. Every now and then, a thumbnail isn’t generated for certain photos. However, these photos do contain the geocoordinates as normal, and when I select ‘Show on map’ in the photo gallery, the correct location is marked there. It’s just that there’s no thumbnail.
It only happens now and then, but it does happen regularly. (And it’s not down to the filter settings).
