This sounds like what I saw when i tested it with another free facilitator, that one wasn't publishing the transaction to the network. I suspect that the current one, payai also may have occasional troubles posting the transaction, though I do see 4 cents dropped to the account since poating, so the thing works at least for some) Coinbase facilitator would've been more reliable I thunk, but it requires a registration, kyc and all that jazz which I don't want to bother with)
