I'm working on a product detail page that contains a 'Table of Contents'. Due to some not so great API work, I'm in a weird situation.
It takes between 10-20 seconds for the app to check if there is a Table of Contents. I want to indicate to the user that it is loading, but I'd rather not draw attention to this failure to load with an animation.
Is there anything better to show that this is actively loading than simple 'Loading...' static text? Does it seems worth it to add a loading animation, but risk having the user look at it early?
Edit: I forgot to mention this is a secondary element on the page. Hope this image helps a bit:
