Hello. We usually release updates within 24 to 48 hours when released upstream (RHEL). We have a handy page that helps us identify if we’ve missing something or version discrepancies here. To @jlehtone’s point, there hasn’t been that many updates being released because the 8.5 beta was released, so there is less incentive for them to maintain some things in 8.4 if it’s not necessary. That, and mirrors can sometimes be an issue. We’re getting a better handle on it as time goes on though.
If you find that you’re not receiving an update whereas a RHEL machine or a CentOS machine has received it, please let us know with an example and the mirror (if possible) that you’re connecting to and we can investigate.
