This isn't so much a question, but a request to fix this behavior in Map Viewer. When you are editing many fields, it gets rather tedious to have to constantly be scrolling back to where you just where. As soon as you hit Done or X out of the formatting, you are back to the top.
You can see this behavior in the video I added.
@Kim_Graham Thanks for reporting the issue. We will investigate further and fix the behavior in future releases!
I second this request- becomes quite annoying when you have many fields in a pop-up that need alias changes.
Thank you for sharing your feedback, we are looking into the behavior at our end.
In the upcoming release of ArcGIS Online, we have made enhancements to formatting fields in Map Viewer! We hope this will improve the experience and are open to feedback.
