I tried to transfer funds from my Jaxx wallet to my coinbase wallet on the 10/11/17. Five days went by then the funds reappeared back in my jaxx wallet. The next morning (15/11/17) the funds disappeared again and the funds haven’t been seen since.
We don't have enough information here to determine what happened. You didn't say, but I assume nothing ever arrived in your Coinbase account, right?
Funds disappearing and reappearing in the Jaxx wallet is not unheard of. It's very glitchy and unreliable; I recommend against it. For a lightweight BTC wallet, I recommend Electrum, which doesn't experience those kind of issues.
I am new to bitcoin and I have noticed on the Jaxx wallet the transaction has a number. I clicked into it and it takes you to another site. The transaction says it has 2 outputs, the 1st is spent and the 2nd larger sum is unspent. It has been confirmed by 6+ miners.
Does this mean the money has been lost in the blockchain as the mempool is full or has the money disappeared and my mobile wallet been hacked.
To confirm what happened, could you post your Coinbase deposit address and the Transaction ID# in your Jaxx withdrawal history? Then we can check on the blockchain what happened, because it sounds like the funds were already sent and confirmed.
