I can't update the app's privacy policy URL. The privacy policy is online and returns a 200 status code.
The privacy policy is here: https://www.micol.life/guide/privacy, as you can see, it's online and returns a 200 status code.
We're having the same issue here, we opened a post about it too: https://developers.facebook.com/community/threads/3635861516682827/
Same issue here. We received a required action warning about an invalid URL violation. The privacy policy URL is correct and returns a 200. Any attempt to update is being rejected.
