Unfortunately, I’m not able to answer that. I’ve been using insync on multiple windows 7 and 10 machines for at least 3 years now with 6 free personal gdrives and one teams. insync 1.x worked pretty much flawlessly. I didn’t experience syncing issues until “upgrading” to 3.x. It has been rough to say the least but it seems to be functioning properly at the moment.
Can you provide more details regarding the installation? Which operating systems experience the issue, google cloud type (business, teams, personal), file types that fail to sync properly. Is your problem that items created locally get pushed to the cloud, but other machines aren’t automatically downloading the cloud files locally? Or is it that items created locally don’t get pushed to the cloud? Does this happen when renaming or changing existing files as well?
When you say “re-syncing” do you mean you manually unsynced and resynced or do you mean you removed the account and re-added as a new account rather than an exisitng account so it bypasses the 'local-to-cloud file matching’ entirely.
Might be better to start your own thread to discuss in more detail.
