iXpand 3 not coping photos from phone to iXpand

 I am having almost the exact same experience trying to free space on my iPhone SE. 

 Was it ever resolved? 

 I have invested $60 and many hours in this project, and have only managed to copy four out of 900 photos. It seems to me that this product is fraudulently marketed 

 Not easy, not fast, not storing the photos that I bought it to store. Have you gotten any solution to your problem?
