I was able to do this once before months ago and I have since had issues editing AGOL data in ArcPro. I start by adding data to my ArcPro project from My Content in the Portal. The data I add are all data that I own and shared as a feature service to AGOL. My data displays in ArcPro, but I am unable to do the live editing on the data that I was once able to do. See the screenshot below for the error message I receive. I have been unable to find any help documents that address this. Have I missed a step perhaps in making this data editable in ArcPro?
