Previously I asked a question about marking sitemap warnings as fixed here:

[Resetting sitemap warnings in Webmaster Tools](https://webmasters.stackexchange.com/questions/78152/resetting-sitemap-warnings-in-webmaster-tools)

I look in my account today and find such warnings and errors are always outdated, and now I want to know which is the fastest method of telling google that I made changes and that all links are correct.

Should I try using the ping URL at google to re-submit my sitemap or do I have to use Google Search Console? Which is the fastest in terms of overall sitemap submission and processing?

I'm asking because I don't want to see random warnings and errors stay in my Google Search console account for however many days it feels like doing it when I make changes to my website. I want to see those warnings and errors gone asap.

Oh, and the number of URLs in the sitemap are about 12,000.
