I have a positive balance on blockchain following a xfer from coinbas3 this morning..now when I go to send from blockchain my go-to wallet Addy has vanished from the drop down (From) box. I'm only showing a private key address and trading account,both with a zero next to them and not my current balance. 1st issue in 7 yrs trying to send btc from Blockchain. Please help me send out successfully from my blockchain wallet. Would be extremely appreciated...my blockchain mobile app is the only way I'm able to view/select my usual wallet Addy when trying to send out but mobile app has never worked as I continually get an invalid address error for every address I'm trying to send to.
