解决办法

Manually re-add the Symbol Rotation field in ArcGIS Online. The field should be added as an integer data type with the field name “symbolrotation” (no spaces and all lowercase). The minimum and maximum values should be set to 0 and 359, respectively, to match what was originally in the solution.
