Question
Do I need to add the https or http protocol when inserting links in articles?
Answer
Links are recommended to be inserted with the https or http protocol. Certain URLs, for example subdomain1.subdomain2.domain.com are saved as a relative path, if the protocol was not added.
Adding the https or http protocol prevents links from being as relative paths, or anchor links in the body of the article.
