Worked great, but not anymore

Im still giving this app a chance. Ive had it for a couple of months and until this month it has worked great. Now, I get missions and my maps are blank. Before my stores would show up. Now, empty. Ive contacted customer support three times. Twice they helped me try to solve the problem. Didnt solve it. Third time the email came back undeliverable even though I was replying back to their original email as told. Im going to keep it but if the problem doesnt resolve itself in the next update, I will be cashing out and deleting and not referring it to anyone any longer.
