Yes tried with wifi and mobile connection.

Made a Jaxx support ticket and they told me not to mine on a Jaxx wallet and to take the private keys and make a new Jaxx wallet and sweep.
I was able to successfully claim more ZEC but I am now having problems with one private key with the most ZEC I have.. keeps saying transaction failed once again.

going to try Coinomi on an IPhone, it seems like a lot of people are having these similar issues on Android according to research.
