App won’t access all the photos in iCould – Photo Collage Pro Editor Review

When I try to select photos to include in my collage, this app does not recognize all the photos in my iCloud that are accessible on my iPhone and iPad, and different photos are accessible if I use the app on my iPhone or iPad. I have 1,092 photos, but the app says I only have 502 when I try to select photos to include in my collage. VERY frustrating and disappointing! Is there a workaround?
