I'm running ArcMap 10.7.1 and Server 10.6. I publish my map layers to our server, then add them to a web map via "add layer from web". When I open the map on an ios device (phone, ipad, mac..), the map will crash if I open up certain layers. It seems to only be point layers. This doesn't happen on Android devices. I've searched and can't find where anyone has had this specific problem. Could it be because of the different versions in ArcMap and Server? If not, any suggestions? TIA!
