I recently noticed that the symbology I had published from ArcGIS Pro to a Hosted Feature Layer had been reverted to just a black dot for all unique symbol values within the WebMap. I was recently making some schema changes to that Hosted Feature Layers data, unrelated to the field that defines the symbology, but this is the only thing I can think would have caused this. This layer had been running without problem since August of 2022. My question is, am I able to restore the symbols for the unique field values using only AGOL, without having to re-publish it out from ArcGIS Pro again? I looked through the new available symbol sets available on ArcGIS Online, and the symbols I need are not available in the lists. They are not complicated symbols, and I have other hosted layers representing the same symbol sets with slightly different colors, that have different defining parameters).
I noticed that I am able to upload a Desktop Style .stylx file to my ArcGIS Online account, and also .lyrx files to my ArcGIS Online account. Is there any way to call to these style and/or layer files from the Styles menu within the ArcGIS Online WebMap to reset the symbology that way? I didn't see that this was possible.
My Hosted feature layer has 2,500 points all of which have photo attributes totaling a file size of about 2GB. If I cannot restore the symbology on ArcGIS Online, is the best method to accomplish this, to download the hosted data as a fGDB and then using ArcGIS Pro, just overwrite the existing feature layer where the symbology had been reverted back to a standard black dot? I am really hoping to avoid doing this as the app is live and in use daily.
I've attached what the symbols looked like before, and what they reverted to.
