Translating and FB Adv

Hello,

i moved from polylang to translatepress recently to have an easier management of my website.
i alway performed facebook advertising without any issue but since i installed translatepress the things changed.
if i make an ADV to a main language page. no worries. but if i use the url of a translated page (in my website /IT italian language) facebook adv give me an error telling me the url used is not “reachable by facebook for analysis purpose”. Of course if i try to follow the link it works perfectly.

Facebook doesn’t give me any help about this. My own try gave me the evidence that main language works, translated language urls work partially (some yes, other no.

Does someone has some advice to help me?
thanks
Francesco
