I confirm this issue too!
Sending BCH unsuccessfull, I got message: Your bitcoin cash transaction failed to send. Please try again.
And I no received BCH yesterday (11/11/2018), but I see 115 Confirmations for this transaction on the bitcoincash.blockexplorer.com and no wallets transaction history, no this money on blockchain wallet!
Receiving address is correct!
Is there a way to fix this? Support is not responding.
