Crunchyroll seems to barely work at the best of times, and when it does, it's still a mess.

All sorts of issues still unresolved for years, including the ridiculously annoying "Finishes playing season English sub, autoplays first season of German dub, which then gets stuck". Still no profiles (nerfing their super-premium offering). Auto-resume points are unreliable, the Android app is hot garbage at dealing with network disruption...

I can only imagine their back-end is mostly Visual Basic running on a single AWS-powered VM.
