Please can you add the Layers parameter to Instant Apps? I would like to be able to share a URL that will open my Instant App with certain layers switched on. You can do this with the Map Viewer, but not Instant Apps.
@SarahNoakes1 you can do this in many of the instant apps using the Share tool. Here's an example of the Media map that shows how this works. You can use the layer list to change layer visibility then use teh Share > Copy Link option and the share link will honor the layer visibility you've selected.
