what is the address the coins are in? I see your screen shot but I cant copy and paste the address form that and I also tried typing it in block cypher manually and it said invalid public key so you need to double check the address’ on block explorer
do you have the transaciotn id? what about a physical backup for the jaxx wallet and not just the 12 word seed phrase? I am pretty sure you can type that seed phrase into a sha256 or sha512 hash generator and hash it twice and that is your private key…
