This PR breaks the Cypress test https://github.com/corona-warn-app/cwa-website/blob/master/cypress/integration/faq.js

Do not merge until Cypress issues have been fixed.

Unfortunately the faq.js test relies on exact text in this FAQ (#further_details). This is another example of a questionable test strategy, but in the short term the solution is to change the text in https://github.com/corona-warn-app/cwa-website/tree/master/cypress/fixtures/copy

Also, the guidance in https://github.com/corona-warn-app/cwa-website/blob/master/README.md#testing says:

"To minimize the occurrence of errors we would ask you to perform all tests when contributing to our repository."

This step was omitted apparently.

Thank you for highlighting the problem and providing a solution. I will review your PR shortly.

Great, one update of the article covers several updates of the app, thanks a million!
Approved.

Since PR #3153 has been merged, this should no longer break the tests, as tested by @MikeMcC399 and me.
