Append tool slow for ArcOnline Users but fast for Administrators

[LindsayRaabe_FPCWA]

We rely on the Append tool to update a number of feature services on a semi-regular basis. We have recently discovered that when appending data to a feature service, the tool works super quick (seconds) to append thousands of records when run by and ArcGIS Online administrator. But for Non-Admin users running the same tool, with the same input & target data, using the same PC & network connection (essentially everything is the same except their ArcGIS Online member role) it is super slow (hours). 

Why????

I even tried a custom role where I toggled the below setting, thinking that looked like the most logical setting that might make a difference, but alas - it had no effect.

Lindsay - a question for you - when you're setting up the append operation for non-administrators or non-owner members, are you using this workflow in the following technical support article?

Hi Robert. Thanks for the link. Drom what I can see, this confirms I'm going about it the right way. We're using Arcgis Pro and the content is shared to a group that our Data Editors are members of with normal edit privileges. I anticipate that if this went the case,  they would be able to Append at all (been using ArcGIS Online for years now so across the majority of functions around groups and data sharing).

I've just opened an ESRI Support case for this issue: 03192745. Will post back with the outcome.

Hi Lindsay, I am having the same issue. Did you get a solution?

[LindsayRaabe_FPCWA]

Not yet - still working on the issue with ESRI tech support. They might be interested in looking at your data too so will make sure they know you're having trouble too.

Hello, This issue could be bypassed by using a shared update group, however, it depends on your Organization's members' permissions, roles, and user types. I found that when for example a Data editor is within a default group the append doesn't work as itself, it becomes multiple individual editing requests instead of appending, that's why it takes too long to load the changes. It doesn't take just one file and post it but each individual edit.

My testing yesterday with ESRI Australia Support found the same results regarding the shared update group allowing the tool to work as expected for non-Administrators. We too couldn't add "Data Editors" to it though. They had to be a "User" type. Hopefully this bug can be addressed soon, as it surely is a bug!
