The second try it passed. Just when opening existing emails, I cannot edit them. The same happens if I clone existing emails. On my other instances I could resolve it by putting on the beginning of each email. This time it did not help to resolve the problem. The button for opening the GrapeJS editor is greyed out for most of the existing emails. Seems I can create new emails without any problems. ---

Hi, the template files change between M3 and M4. You need to define grapesjs builder as an array the template config.

Actually I have no problem with creating new emails using the templates, I have a problem with opening emails I have been writing before. Found out now that he changed them all to the code mode template, and I have just the HTML under advanced settings. Just under Mautic 3 they have been opening fine with GapeJS. What had happened to my emails, and how can I revert that?
