Herman Thank you very much. Now I see where problem is. For some strage reason, there is no DCIM folder on your iPhone, which is standart location for images taken by internal camera for all cameras and video cameras, as well as phones, including iPhones we tested with. In your case folders with photos are placed right under “Internal Storage”.
It looks like we need to add special handilng for this case to Tonfotos, but first we need to understad why this is happening.
Do you know anything about it or why is that? Did you change any settings anywhere that might have this result? Do you syncronize all your photos with iCloud? I did quick googling on why DCIM folder might be missing, and most of the articles suggest it has to do with the fact that photo orignials are stored in iCloud, not on iPhone.
