After few times used it asks for a name and wont let you sign up

I wasnt able to use the perka app because it kept asking for my name and when i gave it it wouldnt work. I deleted and redownloaded, if it doesnt work ill keep it at one star and i will urge other customers and businesses to steer away from this app. Fix the issue. Im owed about 40 points
