Cannot use zero trust feature after upgrade

Yesterday I was testing Cloudflare tunnel private networks using the free tier. In short, I wasn’t able to get it working. I upgraded from the zero trust free tier to add an al a carte Gateway Teams license, presuming it could be an insufficient subscription problem.

Now that I’ve upgraded, I get a warning that I’m using a legacy subscription and access to feature like manage the WARP client split tunnels is inaccessible. I have cancelled the license but it is still active for a month. Is there a way to immediately remove the license so I don’t have to wait a month to test?
