I have the new wallet and I successfully sent 1 kore from Bittrex to my wallet and received it then a few minutes I sent the rest and I have not received them this was over 5 hours ago. I opened up a ticket with them and they said the wallet hasn't synced in 1524 minutes.
I sent 1 test KORE 24 hours ago from Bittrex to my wallet and I am still waiting for it

I spoke to MikeMike yesterday and he is aware of the issue and im sure he and the team are doing their best to get it sorted.
