Ask HN: Revert to old Gmail for G-Suite

(Feel free to flag / delete if you feel this is irrelevant)

I know the new Gmail design has been discussed many times, but I cannot find any recent information on ways people have found to revert to the old design.

I was forced into the new design without warning yesterday, but as a G-Suite user I thought there would be an option to disable it for now? The 'Go back to Classic' option is gone from my settings cog.

Does anyone have any tricks/tips to do this?

(Not interested in devolving into redesign discussion as this has been done many times)
