Worst app

Worst app ever it will only work once and never again. Once you close this app it wont open again and all of your information will stay there and the only way to open the app again is to delete it and add it again I try getting help from Apple Support and thats what they did I backed up my phone and erase all settings and it still didnt work. By way all of my apps work except iMovie. Zero stars if I could
