Hi,
We apologize for the difficulties you are having with the plugin. Please do . the following:
A. Confirm that the time in your database matches the expected time on those links. You may need to speak with your host provider
?
?B. Make a change to this link: https://mustmoveon.com/question-category/finance/ on the backend. Save it. See if the timestamp resolves for that post-type on the sitemap. If it does, you will need to go through each link and make changes to make the timestamp appear as expected.
??This guide explains more: https://kb.yoast.com/kb/missing-or-invalid-date-in-xml-sitemap/
C. ?Once the changes are finished clear your cache (server, plugin/theme, browser, or CDN such as Cloudflare). If you are not sure how to clear your server cache you should speak with your host provider. If you are not sure how to clear your browser cache this guide explains more: https://www.refreshyourcache.com/en/home/
D. ?Then resubmit your sitemaps back to Google. ?We’ve added a guide by Google that explains the process: https://support.google.com/webmasters/answer/183669?hl=en.
Lastly, know that even though Last Mod may not be showing the right time, it is mostly a bag of noise that Google ignores: https://www.seroundtable.com/google-lastmod-xml-sitemap-20579.html
