One professional asked, "A resource in GSC filled with data, except for the links section, 6 days after creating an account, is that normal?"
John Mueller didn't see the need to spend a lot of resources on the links report because he felt it wasn't an area that webmasters should be focusing on.
In addition, the Google employee explained that different parts of the report are updated at different frequencies and when a professional adds a new site, he sees the data selectively, it appears in the following days. Sometimes the cycle can be broken.
