Using Chrome (Version 62.0.3202.94 (Official Build) (64-bit)) in both AGOL and Web AppBuilder Developer edition the "insert image" buttons no longer open a navigation menu. Anyone else run into this, or have a solution?
I've made sure that it's not something as simple as a popup blocker (tried it with popup blocking off completely as well as adding exceptions).
I wasn't able to find the bug report (https://my.esri.com/#/support/bugs) but I am also having the issue. I'm using a Dell Precision 5520 Touchscreen. I encounter the same issue in firefox and Chrome. The click and drag option works when I have my keyboard and mouse attached. I have not tried the touchscreen option.
Add the Lenovo Yoga Thinkpad to the list (Windows 10 Pro). Same bug, with Firefox 66.0.4 and Chrome 78.0. Note that the tablet mode is disabled, and that the laptop is closed (connected to a dual screen).
I'm running into this issue on my Dell Latitude 5290 2-in-1 on the Download CSV button in the Screening Widget as well as on the Insert Image button in the Splash Screen widget. I'm experiencing it in all browsers and in both AGOL and our portal environment (which is at 10.7.1). I contacted Esri and they created a second BUG for the Download CSV button not working in the Screening Widget (BUG-000131723).
