Neat app but for some reason the "image downloand" stopped working – Picter - Create & Edit photos, Collage Maker Review

Neat app but for some reason the "image downloand" stopped working. reinstamling didn't help. edit: fixed, but I can't figure out the dark mode. there is no option for it although people claim that there should be.
