W3I offers ~ Bug in multiple devices

Hey :)

I know that on some tablets W3I offers don't work that as they should but i tried on Iphone... and recive 15 free plat... now all offers r "paid" so i look on history and there r many of "free" offers "available"... Under the history is button "load more" so i clicked.. and it loaded more "available" offers in history... i swiched to main window and there were still only "paid" offers... what should i do to "unlock" that "free" ones? Please help me as quickly as possible.
