Simple Photo Folder 4+

It doesn’t seem to transfer information and data to other devices! I download app on my phone apple and just blank, what am I going wrong?? Thanks. Could be great little app.

Just what I wanted.
I’m an artist who organises their photos in albums very carefully with appropriate titles so I can get straight to what I want just using albums. But apple seem convinced that this is old hat and have consistently ‘downgraded’ your ability to simply go straight to your ‘albums’ in ‘photos’. For me, ios 12 took the biscuit. Since ios 12, the ‘search’ button in the Apple photos app (which I have never used or needed too) has, strangely, taken pride of place on the bottom right, where the most convenient and most-used icon in ‘photos’ should be. Why on earth Apple thought it was a great idea to move ‘albums’ (your most-used icon) to the left and replace it with ‘search’ (the button you would only use in desperation) is a total mystery. It’s the single dumbest thing apple have ever done with the photos app, as it now means going straight to your albums is less convenient than it used to be. I used to just move my right thumb over to ‘albums’ and that was fine. Now, using an ipad pro, it’s a stretch.
This simple app solves that. It just takes you straight into ‘albums’, where you want to be anyway without any unecessary extra step and with no ‘for you’, ‘memories’ etc rubbish. Your ‘All photos’ roll is right there at the top, followed by your albums list. Simple.
I just wish this had a better icon so it looked better in my doc. If the developer wants one I’ll make them one for nothing.

I’ve started transferring all my business photos to here but it’s just stopped adding them after about 30.
Is there a limit? How do I solve this?
