Identical issue, which I’ve raised several times since last October, no solution to date, despite sending logs, letting them takeover my computer and reinstall an old version to see the issue arise themselves and discussing with their Windows engineer. The last response I received last January was “Unfortunately, we are occupied with higher priority tasks at the moment. I will try to work on this issue next week.”
No news since.
The real problem is that I don’t always get or see the error pop-up message,
Insync just turns itself off every single time there is an autoupdate fail, I have to manually update it for it to run again.
And of course, I only realize it when angry clients tell me they don’t see the documents I’ve said I shared with them.
Please, please, Insync, solve this problem that some of us have been experiencing for a long time !
