Suse Patch Finder – SLES SP3

I have been using the Suse patch finder (SUSE Patches) to get information on patches for my various development systems.
It works great for SUSE Linux Enterprise Server LTSS 15 SP2 and returns hundreds of patches that I can review. But for SUSE Linux Enterprise Server 15 SP3 it only returns release notes and no individual patches. I have active subscriptions for both. What has changed for SP3 (and SP4) that I can no longer search for the patches? Can anyone point me to what has changed? Any documentation? Or where I can get the patches now?
