Specific case. When “Compile using Android Version” is set to Android 9.0(Pie) and when running on a device that has Android 9.0 as the OS – Bing and OSM maps will not display.
Works fine on earlier versions of the OS and compiling with an earlier version also works on all platforms. Obviously I have a work around of simply using the 8.1 compiler. Just making you aware of this issue.
