I recently updated a Panasonic toughbook running Windows 10 to the latest version of Survey123 for Windows and the stylus for some reason no longer functions. Selections can be made with your finger it just doesn't recognize the stylus. This wasn't an issue with the previously installed version (not sure of the exact version it was but it was 3.x) and I installed Survey123 Classic just to satisfy my curiosity and it still works as expected.
Thanks for all the help testing this. The fix is now available in Walt Disney Release (3.7)
