If you have MacBook with Touch Bar and you use it to access Windows on Amazon WorkSpaces then pressing fn + (function key) does not do anything on Windows. To get around this problem you have to update the below settings.
Go to > System Preferences… > Keyboard and update the settings Touch bar shows to F1, F2, etc. Keys.
Downsides to this work around:
- The function key F11 still goes to Mac and shows Desktop on Mac
- You lose direct access to App Controls via Touch Bar
