Button DP Alt sharing fails due to windows projection mode "PC screen only"

Issue

Windows remembers the last projection mode used for a connected display (here the 5^th Gen Button).
If that last mode turns out to be “PC screen only".

 
 
The Button is in a deadlock the next time you plugin in the Button and try to share. 
You will see nothing on the screen while the LED from the Button and Hub is in sharing state with red color. 

You can for example run into this situation by pressing WIN + P and select PC screen only while sharing.

Workaround

1. Plugin the Button
2. Make sure the Button LED is steady white
3. Press the Button to share and switch projection mode WIN + P to Duplicated in 7 sec.
4. Windows would memory the projection mode to duplicate and recover the issue. 

Remark: 
The time frame to correct is only 7 seconds.
Because the Button waits for 7 seconds to see if some data comes in, so if in that time frame the user changes the Windows display to Duplicate or Extend, the Button is recovered.
