Ever since my computer updated to build 1703-1709 (Windows Creators) Box Sync no longer works. I can download files with no issues though a little slow, but can't never upload anything, 2 files out of 50 if I'm lucky. Reinstalling doesn't help, I tried the old way with drag and drop directly on the website but still there's a chance that I'm going to get "Something went wrong and couldn't upload" on some files, which I never had this issue before on older builds. Let me also add that while Box Sync is having a conflict in trying to work it literally kills my internet and I can't browse at all while it's working. The moment I close the application my internet goes back to normal.
I originally reverted from 1703 to 1607 but since I had to reinstall Windows I know have 1709 with no other option than to try to find a solution to this, but for know I haven't even find something similar to what I'm going through right now.
