Hi!
I thought I would share since I went thru a little bit of a maze to turn off the auto-renewal feature for Gemini Code Assist Licenses. I was testing out the enterprise and wanted to see difference btwn individual and enterprise license and found that enterprise features were great but you have to buy 10 licenses. I signed up for the free trial and made sure to setup a reminder to make sure that I turned off after the 30 day period.
Use the following picture to guide you thru the screens to turn off auto-renew feature.

On The Manage Subscriptions Tab - Make Sure To Select The Subscriptions and Then Click Subscription Settings! I got confused b/c License Mangement Page pulls up by default which is the wrong page for turning off the auto renew feature.
Hope this helps!
