Your privacy policy url and accept all after you are being aproved you can change any thing that you dont want to be shown on your website.My site is approved. You need to create a policy of use, conditions and have content that has attendance. Separately, your site must be confirmed on Google that it is your property and you must wait before it is approved. Everything is described in the Google documentation.
Some times it can take days even months but like me it took minutes. I have admob register to and all that I have my site on firebase not just the apps even on google developer I even have it registee to make campaigns to be shared so over the web that is by paying for showing my site that campaign service is not free. I even have my sites registerd on different search engines like Google Bing etc even on China search engines
