Annoyed and awful

I downloaded the app a couple of hours before my flight. I wanted to check in online and check my flight status. The flight time displayed as actual takeoff was much later than scheduled; thinking it was delayed. I had a hard time trying to check in as well. I crossed checked the info online on a laptop but it displayed no data and was hard to check in as well. I showed up to the airport a bit too late for the scheduled time and with enough time for the "delayed" flight. I ended up missing my flight due to the gate border closing according to the scheduled time. I also have to wait a day later for flights. It shows I shouldnt rely on technology but this app accuracy needs much improvement at least.
