App Store connect shows error "you must provide a privacy policy url" even the privacy link is provided

I am submitting my app on App Store Connect\My App page and when I submit for review, it shows error on App Information: "You must provide a Privacy Policy URL." even I have pasted the link to the website show the privacy policy there. I have checked the link using

https://developers.facebook.com/tools/debug/sharing/

and they show no error. Do you know what could be the reason and how to fix it ? Thank you!

You need to submit the privacy policy for each localization seperately.

you have to provide privacy policy url in iTunes Connect --> your app --> App Information Tab inside.

see below screenshot for more details :

if you have added any other language then you have to add privacy policy in that language also. please check it
