Thank you, I will try…

Thank you for your help!

Ooops, I did not expected this behaviour, thank you!

So, when I create new page in Advanced Layout Editor, I will not be able to edit it in standard TinyMCE Editor?

But older pages (with other shortcodes) are automatically loaded in Advanced Layout Editor? And when I change them, I will have two different versions? One saved in Advanced Layout Editor and one (original text) in TinyMCE Editor?
