Good Afternoon,
I'm not sure if this is just a bug in Microsoft Edge browser or not. I was trying to add Forms to the webmap in ArcGIS Online, and I cannot click OK or x to close out the configure form once I added the Group to the form. But if I just open the form without adding any group or data into the form, I was able to click ok or close. But once I add anything to the form, it will just stuck in that page unless I click Refresh, which then I lose the edit of the form.
Everything works okay when I switch to Google Chrome. My coworker also experiences the same issue. Please see the screenshot below.
