Greg!
Hope all is well, big fan and avid user of pagebuilder and purchaser of the vantage premium theme.
This issue that Adrian posted is still ongoing for me. In particular if I type about 2 sentences of text the TinyMCE text saves and is not an issue. However when i add images in TinyMCE and text with different details in the box…the dissapearing of content still occurs.
Running the new 1.4.6 pagebuilder and 1.3.0 Tiny MCE
