Cannot install Zoho WorkDrive client on MacOS

Cannot install Zoho WorkDrive client on MacOS

I started using Zoho WorkDrive in October 2019, but cannot get the application to work on my Mac. The program prompts to login, but never completes. I've tried later versions of the client, and even upgraded to the latest MacOS release, but the problem persists.

I've had Zoho support login twice now to replicate the problem and do some debugging. Then... silence.

I've chased numerous times, but all I get is assurances that this is being treated as a "high priority". It obviously isn't because otherwise it would be fixed by now.

Zoho Support - please do something about this!
