Bitpay Invoices expiring! Transactions not showing up in the blockchain.

[Abigaille]

This has happened to me 3 times now!  I get a Bitpay invoice with a 15 min timer, I send a payment immediately, but the transaction never shows up in the blockchain and the invoice expires.  And the coins have left my wallet! It's happened paying from Multibit AND Coinbase! I hate this! Sometimes it's instantaneous, but other times it randomly does this crap!  Is this a flaw with the Bitcoin protocol? Why isn't it more reliable??? So fing frustrating!

Funny I sent another payment out from Coinbase and it showed up immediately in the blockchain and the one to Bitpay still is not showing. I wonder if they don't want to send transactions to their competitor .

Is this a flaw with the Bitcoin protocol?

No, this is a flaw in the services you are using.
