I have an Email that contains various ContentBlockbyID references. The Email looks fine when I open it in send/preview. But in view mode in content builder or when I configure it in a Journey, I only see the code like
%%=ContentBlockbyID("583")=%%%%=ContentBlockbyID("586")=%%%%=ContentBlockbyID("587")=%%%%=ContentBlockbyID("588")=%%%%=ContentBlockbyID("517")=%%
I would actually expect that the code gets rendered. Any hint?
