Hello @pexel
Thank you very much for using our plugin. The main change is related to the support of AMP pages. AMP pages load the forms into amp-iframe tags. If you configure to load the form into an iframe tag, it is not possible to resize the amp-iframe when the form is loaded by the iframe tag, or when you resize the browser or the form height changes since dependencies. The plugin update chains the resize process from the form into the iframe until the amp-iframe tag in the page. Another issue the update fixes is related to the cookies and nonces. The AMP requires that the main page and amp-iframe content belong to different domains, which provokes the nonce validation fails. Embedding iframe tags into amp-iframe tags solves this problem because the main page and the page loaded by the internal iframe tag belong to the same domain.
Best regards.
