I'm trying to create a SIMPLE map in Pro for use in Explorer. I've generated the MMPK in Pro and uploaded it to AGOL, but when I try and use it in Explorer I get - Invalid Map!
The only thing I've done is added a POI Locator. All I need is to be able to search a layer, and the simple Locator doesn't work for whatever reason, so I tried to create one instead.
Why is this so hard?
