If you are using the touchscreen functionality of a touchscreen computer, you may experience issues dragging blocks into the code pallet. Your browser may be set to change page or go back a page when you swipe which prevents you from dragging the blocks over. You need to turn this off to use Tynker with the touchscreen functionality of your computer.

To fix this on Chrome:

  • In your browser, go to:  
    • chrome://flags/#overscroll-history-navigation
  • Select Disable from the drop down under "Overscroll history navigation"
