I cant belive i waited days for that reply. Unreal!!
I deactivated sitemaps and installed xml sitmaps and no issues.
Im also having issues where the meta data i add using rankmath is not used by google search results, probably only 1/10 of my meta datas are correct. Im starting to think rank math has more bugs that lake in the amazon rainforest.
I have tried following all other issues people have had regarding sitemaps.
No cache running.
saved permalink settings.
save button in rankmath sitemap settings.
disabled sitemaps and re enabled.
