Version 78.0.262.0 (Official build) canary (64-bit) - still happening in Version 78.0.266.0
Windows 10 build 18970.1005
in the normal Edge insider window it's okay and clicking on the smiley button opens the mini feedback section normally, but when i click on smiley button inside the application guard window, it opens the Feedback Hub app instead.
Thanks for the feedback! Please note that this behavior is by design for Microsoft Edge Application Guard. The Windows Feedback Hub App captures more diagnostic information related to various components used by Application Guard including Microsoft Edge. Please use the "Recreate my problem" option in the "Add more details" section while filing feedback. And thanks once again for trying out it out!
