My screen was broken & it would not display flight info or movies. Wifi hotspot was also broken and did not work. At YVR, I was not told I had the option to manually fill out a custom declarations form. Instead I was encouraged to use a privacy violating machine with facial recognition. This made me feel like a prisoner & it was not a pleasant experience.
