Hello. When exporting, pages are saved to a .json file. But nothing happens when importing. How I do it: I open an existing page, do an export, close the page. I create a new page, assign a name, save the page, import - but nothing happens. I read the documentation, do as it says, but there is no result. I have two SPPB pages that need to be combined into one new page. How to do it?
