Yes, its begin work more stable but too slowly. I couldn't sync 60 Gb (1 millions files) for one week. Now its sync only 22 Gb. I frequently see status Indexing, on main server I see 40 Gb send to another device but on device I see 22 Gb and do not download anything. I have 5 days trial, and I do not know whether it is suitable for my task.
I have the same problem on 2.1.1 version. I already test It on 3 different servers and get same result and GUI do not responding. I have more then 8.6 millions files (500 GB) for sync. Is any solutions for this problem?
