Trying to create a set and app keeps crashing

Too bad for you. I saw your ad on my Instagram account and immediately thought “cool”! Download app and can’t even select more than 5 pictures, keeps crashing. What a waste of your advertising budget! I probably wouldn’t have bought any anyway... $60 US (like 80$ Canadian) that’s insane!
