My Search Console is old. It has been reflecting links and errors dating back to URLs from 2013/2015. In the new website, I have configured everything correctly and made sure there are no internal links pointing out for any old/dead URLs.
Summary of GSC:
The problem is, with the errors, it just says "Validation Passed/Started" but when I inspect the pages, it does not show an error?
PS: I have read the similar questions and understand that if there are soft 404 or not found that keep coming up with old URLs, important ones have to be 301 Redirected. I have did that but still I get these errors. Submitted them in the "removal tools" as well.
