I looked over the video. It is nice to see a compressed video, but it was still hard to understand what to pay attention to inside a 20 minute video. It would be great if you added callouts to the important moments so people could easily jump to the important items.
Is Firebase a requirement? I tried to create a sample app and was immediately told I needed to setup Firebase. I didn't see a way to skip that step, but perhaps it is because I used a sample template? I would prefer to use GraphQL as a backend, and am not sure if the full Firebase stack (auth, storage, realtime) are used, or if you can swap pieces in and out when desired.
Congratulations on your launch!
