google adsense problem ?

hi guys i have problem ,


i create a wordpress and i add to it ads , and the ads are active and i add this see to my adsense website and verified that my . (my adsense is old 2015)

the problem is the ads doesn't showing whether add plugin or not , sometimes one ads showing but after reload the page disappears !

please where is the problem ?

now google doesn't show ad like before.
they only show ad if your content is crawled by google adsense bot.
this is for them to prevent low/thin contents.

now it takes time.. give it a few weeks, but for some post, if we're lucky enough, the ad will show within 24 hours..
so my suggestion is keep posting, and try to index it first on google, by time the adsense crawler will come and the ad will show
