I went to my FB - gotten two ads. Searched for them in this - for the first one: - wasn't able to find it by title, url, company name, nothing, regardless if filtering by my home country, or country I'm at currently - second one - the Economist, showed 12 results, with an option to Subscribe to each one of them; what does that mean? shouldn't I already be "subscribed" to at least one of those?
