Screenshots no longer editable? – Foodie - Filter & Film Camera Review

I love this app. I use it to take/edit images all the time. For the past week or so, it will no longer allow edits to be made to any photos that are actually screenshots. Example: take a screenshot from a friend’s Snapchat - that image cannot be edited in the foodie app. I’ll apply a filter, and when I go to save the image, it will say “unable to save photo.” This error message ONLY reads when I attempt to make edits to a screenshot, no other types of images. Please help! I love this app!
