Suddenly won’t save any photos? App is now useless – TouchRetouch Review

I’ve used this app for at least a few years now and suddenly, any time I try to save a photo, it says “photo not saved”. This glitch or whatever it is makes the app completely and entirely useless and I’m really bummed about it. If someone could reach out and offer a fix, that’d be fantastic.
