Why isn't ArcGIS Pro updating my creator field with tracking editing enabled on a feature service?

[James_Whitacre]

I am editing data in ArcGIS Pro directly from a feature service hosted on ArcGIS Online that has editor tracking enabled for both time and user. I appended a bunch of rows using the Append tool, which was successful, except the Creator and Editor fields did not update with my user name, however the times did update. Does anyone know why this isn't working? Thanks.

How many characters are allowed in your Creator and Editor fields?  How long is your system username?

I just did a quick test appending a feature from a local feature class to a service and the Creator and Editor fields populate.

The field lengths are 50 characters for both. The usernames are all shorter than that. It is definitely weird...

James, I think that logging a case with technical support is a good idea at this point as this will require some troubleshooting!
