One of the most interesting things about instant apps is that you can switch templates simply by changing the URL. E.g., "arcgis.com/apps/instant/basic/index.html?appid=xyz" and "arcgis.com/apps/instant/interactivelegend/index.html?appid=xyz". This is particularly useful because some templates have been deprecated and should be switched to another template. However, even if you can view another template by changing the URL, you can't configure that template. Even if you change the data source URL on the instant app's item page settings, it still doesn't change the underlying template associated with that AppID. I'm wondering if I'm missing something or if you just can't truly switch templates without starting from scratch with a new AppID.
