Power BI ArcGIS error in iOS: undefined is not an object...

[jrdunson]

Hey all... 

Have an ArcGIS map that works ok in windows, but not on iOS (iphone or ipad)... the map  gives this error: 

undefined is not an object (evaluating 't.labelExpressionInfo.expression=e.labelExpressionInfo?.expression')

A user can close the error, but when the map is moved, the error pops up again

Can anyone help with steps to troubleshoot?

Thanks, 

Jarrell
