Cache issue with NuGet publish and Nexus groups

Version:3.39.0

When we publish a NuGetto NuGet.org, it is not immediately available in the proxy repository So far I understand there is cache on the proxy and I need to clear it on this proxy, nothing strange.

But what is curious is that clearing cache on the proxy repository is not enough, I also need to clear the cache on the group.I find it inconvenient because on a group there is no option to say “clear cache every n minutes” and therefore I need to do it manually.

Could someone tell me if it’s normal and/or how I could improve this workflow?
