We have a Feature Service in ArcGIS Online that has a field called "Description". This field had the default 255 string length. We also have a few different layer views referencing this item with different options and filtering turned on. We recently had to increase this field length to 2000. What we did was create a temp field and then calc the values of "Description" into this temp field. We then deleted and re-created the "Description" field and calc the values back into it. The problem is all the layer views referencing this feature service still have the length set at 255. Even though the original service now shows 2000 for the field length. Is there any way to force the update of the layer views service definitions to reflect the length update?
