It seems that items that link to game information work on the browser and only for the selected item, but when you loaD your character and select the item (either in the browser or on the app) the embedded link does not show (it’s not orange - it is just text).

I am trying to equip the figuring of wondrous power (golden lion) and the link for the lion just doesn’t show up. 

Those internal links are called “tooltips,” and they do not function on the character sheets. You can load a lion under the Extras tab of your character sheet.
