I have today just un-installed Insync from my PC and am now happily running with the native Google Drive File Stream app.
For me, it was your lack of making it easy for user to choose if a file/folder was available offline or online only that made me change. Sure, you could go through the Insync App and choose folders that should be synced to the PC - but that’s cumbersome. I want to open File Explorer and see ALL my data, even if it’s online only. I don’t want to have to navigate through the InSync app.
So thanks for the few years of a good product, but you’ve fallen behind. If you get back in front I may be back, but for now, Drive File Stream offers me everything I need.
Bye bye, might see you again some time.
