I am a new user but it seems that the app doesn't want me to purchase any of the products! Every time I use my voucher, it says that the voucher is invalid but its not! Yet, if I wont use ANY voucher, its still an error. I already installed and uninstalled the app, I logged in and out, restart and clear the cache on my phone and change wifi connections but still nothing happened, I CANT STILL PLACE MY ORDER. Please fix this. Its so annoying.
