Hi Jason,
I apologize for the late reply, I was on holidays.
Thanks for the kind reply, I rechecked configuration on the Developer Console and I found the setting to enable the Gmail API. Was a bit confused because I didn’t enable it the same way I did on my old account.
Your plugin is super simple to use and I would say the Google Developer Console is hard to navigate and not as intuitive as your awesome plugin.
Very happy with your support as well, I wish you the best for your future success with this plugin and any other developments you do.
Thanks again!
