Hi,
It seems we’re lot here to have issue with these new release.
Personnaly, two weeks are passed since my contact with support and my synchronisation problem is not resolved, i’m probably not alone in this case 
I cannot work, so please can we have some a least some news or a date from your support about a new release which correct this bug ?
Best
@reyman I really understand your frustration. Our engineer’s are working hard on fixing these issues.
I have cc’d our Linux engineer @lpugoy.
Thank you for your patience. 
@reyman Apologies for not replying sooner, I was on leave for the past 2 weeks. I will take a look at your issue again.
Thanks @lpugoy, problem solved.
For others user with never ending loop, check the rights for your files,
and make a sudo chown usenamer:username -R . on your folder to resolve this type of problem.
