I installed bittorrent sync on a QNAP NAS HS-210. The version number is 1.1.82. Upon opening the app it asks me to agree with the usual legalese and then a window comes up which I have never seen before i.e. it does not come up on my synology NAS. I attach it here. No matter what I try. I cannot get BT sync to start and create folders on the NAS. Any suggestions? Thanks.
