Deltadoc333, thanks for reporting this bug! Can you please include a screenshot of the error message? Is the error message returned by Citrix or by Duo authentication? What version of Android is your device using? Can you successfully log into the Citrix webportal using your device's Chrome browser? I believe Chrome also hard coded its User-Agent string to report "Android 10", so Citrix or Duo might be checking the Android version for Firefox but not Chrome. Can you please share your device's Chrome User-Agent string? An easy way to check your browser's User-Agent string by Googling for "my user agent".
