Bugs in content types

Hi,

I am new using h5p. 

I create a content: Fill the blanks: if I insert the code using iframe it works fine!

If I use h5p embed shortcode, the content is not visible. [h5p id="17"]

Wordpress 5.4.2

PHP versio 7.3

Wordpress Theme: Generatepress 2.4.2

define('H5P_EMBED_URL_ALWAYS_AVAILABLE', true); is added in wp-config.pphp

h5p Versión 1.15.0

I attach you h5p settings and screenshot in Chrome inspection code.

Tested Browsers Firefox and Chrome

I tried H5P Interactive Book and is so impressed on the results in web browsers. I am beginning to adopt it as my standard way of presenting activities because it is so neat and can contain all other H5P contents. I understand it is just on its beta phase so I just have to enumerate some of my observations. These are some of my observations

The content can not be viewed in Android Moodle App.

Bom dia, não consigo incorporar um iframe no moodle institucional da universidade na qual sou professor. Estou tentando com um simulador do Phet.

Há algum tutorial?

Obrigado
