1.4.x Does not work anymore for me either. Running MacOS 10.13.3, tried 1.4.4 and 1.4.3. Same issue, syncs 50 - 200 files, then just stops. Really frustrating when trying to sync 9k files and folders quitting and restarting the app, got it down to 5k over the last 4 days before I saw this post though. Thank you
When I downloaded and tried 1.3.24 it worked again. Seems the current solution is to downgrade to 1.3.24.
Thank you Alp_Ozenalp.
