    Maybe a little late but in case someone else is wondering how to manage this... What about using a template?

    you could for example use something like:

    
      

    {{course.description}}


    Learning Objectives

    • {{objective.text}}

    Takeaway

    • {{takeaway.text}}
    Loading stuff...

    so your ion-card-content will be hidden, showing the #template, until the async pipe is loaded.
