What is the proper workflow to avoid addition of unwanted CreationDate_1, etc fields when working in AGOL? If the CreationDate and other edit tracking fields exist in a feature layer when edit tracking is enabled, it will add a new set of fields with the same aliases (difficult to tell them apart) but with _1 appended to the names. It will also populate these fields with the date and time when edit tracking was enabled for existing data. The layer had existing values in the original fields when it was uploaded from ArcGIS Pro but it won't re-use those fields. I can maybe see why it does this (to avoid overwriting user data) but it makes it difficult to start with existing data for which you want to maintain the old tracking in a layer. If, for example, you want to filter on date created. You have to choose between using CreationDate for older data in the layer and CreationDate_1 for the new data in the layer.
