I got a response this morning:
What seems to be happening is that while Insync starts, the tray icon for some reason doesn’t show up. By the way, what version of Insync are you currently using? And could you please share with me the logs at ~/.config/Insync/logs.db?
Unfortunately I’ve so far been unable to replicate your issue – using Ubuntu 16.04, Cinnamon 3.6.7, and Insync 1.3.22 OR 1.4.3.
For now, one possible workaround is to disable Insync from starting at startup (uncheck it from the Insync settings) and just manually start Insync.
If you upgrade to Insync 1.4.3, then another workaround is the newly-added show/hide commands, i.e.,
$ insync show
$ insync hide
I will continue investigating and let you know of any findings ASAP.
Not looking good. Free trial ends in 3 days, and I don’t intend to pay for something I have to manually start every time due to a bug.
(My bad not mentioning the Insync version, which is 18.104.22.168179, but really they should have asked for that and the logs at least a week ago.)
