while i am imprting the html file it is giving an error "500: Content validation failed. Please try again later" "This HTML is not adapted to the editor. It will be edited in compatibility mode"
@mysteriousman, You will get the message if you import an HTML file rather than a zip file that contains assets, etc. Once you import the html it will be in compatibility mode and you can convert it to email designer mode to start using email designer functionalities like structure components, and content components.
