We upgraded our on-prem Provisioning Servers from LTSR 2203 CU5 to CU6 in mid-July (along with the rest of the Citrix infrastructure.) Ever since then, I've noticed the Citrix Licensing console shows zero licenses used when it used to have one used per booted VDA. I added access to port 8083 on the license server from the PVS servers and rebooted all the things, but there are still no licenses used. "Netstat" shows an active TCP connection to port 7279 on the license server, same as it always has and I don't see anything obvious in the logs/events. Anyone else run into that issue, by chance?

I have the same issue and raised a question with Citrix. Have you by any chance got "Citrix Cloud" selected as the license type on the PVS farm properties? This is what we have set. If so, switch it back to "Citrix Virtual Apps and Desktops". They've made this very confusing, as this functionality won't be working until CU7.

Good thing to check, but the setting was "Citrix Virtual Apps and Desktops" before and after the upgrade. I suppose we should upgrade the license server before contacting Support. Build 53100 just came out last week. I don't see anything in the release notes, but you never know.
