I had the same experience within an app to manage doctors appointments on iOS. For some reason I was locked out of the app by cloudflare and I ended up having to call my doctor's secretary to move my appointment. It took 15 minutes on the phone for something that should have taken less than a minute within the app. Even my friend who worked for that company had no way to fix it. I don't know whether to blame the app developers or cloudflare here.

I wouldn't call Linux an obscure use case, it's particularly great for workstations and old laptops that struggle with running Windows.
