Switching from App Engine Flex to Standard

Question

I created an App Engine Flex NodeJS app, not realizing that there is no free tier. So I decided to switch to App Engine standard. I updated my app.yaml, deployed, and everything seems to be working. However, I deployed this a couple hours ago, and I still have 2 compute engine instances running. Is there something I need to do to shut those down, or did I just not wait long enough? I don't want them running at all because I don't want to pay for them, especially since the standard app doesn't use compute engine at all.

I tried going to the Compute Engine tab in GCP to see if I could do anything there, but all I get is a "Create instance" button.

Check the Versions page on the Google Cloud Console and make sure that the old version is deleted and that traffic is going to the new version. It may be a good idea to use a new version for the standard env.

Then on the Instances page check if the respective instances are running and shut them down if so.
