Placemark photos not showing up

When I try to look at a photo I've uploaded to a placemark, the app crashes ("Avenza Maps keeps stopping" with "App info" and "Close app" as options). Under "Uploaded photos" it also used to give a preview icon of the photo but now shoes a black and white map with pins on it. Wondering if there is a bug in the program or something wrong with where my photos are stored, etc.

I use this function a lot, so would be great to fix!
