Site plan overlays

Having an issue getting the site plan overlay to display on mobile device but desktop app works great. Also, is there a way to export a map with a site plan overlay as a custom export?

Sometimes it helps just to sign out and back in or recycle power on the mobile device.

It seems it works through the mobile browser at but not the app. I see the ‘overlay’ section on my iPhone 6s+ and my iPad Pro (both up to date) but no overlay present, screengrab uploaded here

I don’t see where to add this App? when I search overlay there isn’t anything that allows to up load a file to place on the map.
