Crash during Pan ("Scale is less than or equal to zero")

JeremyBridges — Wed, 20 Sep 2023 15:44:13 GMT

In a Xamarin.Forms app, we see some customers encounter a crash that results from a pan on the map. We don't know the specific reproduction steps. So, I'm reporting this here for an eventual fix. This doesn't appear to be catchable in managed code. I'd love to see this kind of issue dealt with internally when the cause is something so mundane as panning the map. Error details and stack trace below. Thanks in advance!
