Mobile Checkout Error - Not Carrying Data


Since I had my last upgrade and server change done (las December), some customers are not able to pay using servired payment option, when they click "place order", the bank page opens stating that no data where carried, the servired payment did not receive the order amount, customer info, etc., and so, the store resolves it in error.

Also, I'm using the old step by step checkout.

This only happens in most of android phones, not all of them, but they are enough to make me loose about 10% of the sales daily.

Any ideas are welcome!
