The generated iFrame is blocked by the browser for security reasons.
This is caused by the fact, that the URL in the generated code starts with “http”, even if the URL, you provide starts with https:….
I fixed it in my installation by opening ‘komoot.php’ with a texteditor, searching all ocurrences of ‘http:’ and replacing them by ‘https:’
Works fine for me. (WordPress 5.8)
