I cant see AMP ads

No.

Please check documentation:
https://adinserter.pro/adsense-ads#amp

And now?

I had this configuration before and didnt work for me.

It looks OK.

Although the settings are ok, the ads are not displayed … Here is an example:

https://bdebelleza.com/belleza/tratamientos-corporales-a-medida/
https://bdebelleza.com/belleza/tratamientos-corporales-a-medida/amp

Ads on non-AMP pages are inserted and displayed.
You are inserting amp-ad script on non-AMP pages – it is not needed.

Code for ads on AMP pages seem to be properly inserted.
amp-ad script on AMP pages is missing.

Please check documentation on AdSense on AMP pages.

Now is ok?

https://prnt.sc/jtnd3d

amp-ad script on AMP pages is still missing.

I add this script in the settings of AMP plugin:

<script async custom-element=”amp-ad” src=”https://cdn.ampproject.org/v0/amp-ad-0.1.js”></script&gt;

Its correct?

Now it seems the script is there.
And the ads are showing.

Ok, thank you very much for your patience.

A greeting.
