Feature layer overwrite not updating item properties and giving warning

[rwrenner_abtglobal]

I am using a notebook in ArcGIS Online to overwrite a feature layer (with code excerpt below) and a couple things are not happening as expected:

1. None of the item properties are updating through the overwrite - is this expected? It did work the first time when initially creating the feature layer via the same to_featurelayer method (and overwrite=False).

#define feature layer properties
item_properties = {"service_name" : "Sample Stations test", #this only gets added the first time service is published. Needs to be unique.
                   "title" : "Sample Title", 
                   "tags": "tagone, tagtwo",
                   "folder" : 'Script Outputs',
                  } #none of these are updating in overwrite

#publish sdf to feature layer 
lyr = sdf.spatial.to_featurelayer( 
    title=item_properties["title"], 
    gis=gis,
    tags=item_properties["tags"], 
    folder=item_properties["folder"],

    #only when creating feature layer:
    #service_name=item_properties["service_name"], 

    #only for overwrite:
    overwrite=True,
    service={"featureServiceId" : "ITEMID", "layer": 0})

item_id = lyr.id
url = lyr.url
print(f"Feature layer item {item_id} updated: ", url)

2. The overwrite itself is working although I do get the following warning message. How can I avoid this warning? And is it related to the item properties not updating?

Warning 6: dataset /tmp/tmp6a5ebhyr/ae9b78.gdb does not support layer creation option TARGET_ARCGIS_VERSION"

Would appreciate any suggestions! Thanks.
