I did try it and it works in ArcMap.
However one thing puzzles me - if I add a new attribute field in arcmap and then sync to the AGOL, the new field is not shown/reflected in the HFS.
Like wise if I add a new field from AGOL to the HFS, I can see the new field in the browser, but when I create a local copy the new field is not is it.
Is this to be expected?
Otherwise I can change geometries and attributes OK.
