Unable to find Enable developer add-ons for my account checkbox

Question

I'm working through the quick-start for a Gmail Addon.

https://developers.google.com/gmail/add-ons/guides/quickstart

When I try to Install my developer addon I

1. Open the Gmail add-on settings tab
2. In the Add-ons tab, make sure that you have selected the Enable developer add-ons for my account checkbox

However there is no checkbox...

Is this edition limited? Do we need to do something else to enable this?

Thanks for your help, Paul C

Answer 1

Apparently there is a bug for GSuite admins and they cannot see that button or add addons right now.

Try your personal gmail for now.

Answer 2

There is an issue open with Gmail https://issuetracker.google.com/issues/68234732

I have contacted the Gsuite team, will update the answer once I have something solid.

Update (Dec 19, 2018)

Looks like this issue has been fixed, I could get it working on Corporate and Personal email.
