Unable to link Google account

Hello @xanthope
Thanks for getting in touch,
Can you confirm you are using the latest version of the plugin,
While checking in test environment, it seems that i am able to authenticate easily,

If you want then you can check out here, temp site will be created and you can configure and check.
