I've been posting in this subreddit for years and always see a few common posts.
What ATV device should I buy? Help me with my crappy Chinese box. This app from popular network is not working.
I would say the first two scenarios are handled well but always see an odd lack of people giving proper advice for the app issues on official ATV devices.
I mean there are "some" things we can do to help like suggesting app data is cleared, etc but in reality we can't fix broken apps. I also see it's just the way it is replies.
#####However, the overwhelming right answer is to direct the user at the support email in the app listing (or other customer service options).
Most people having issues don't realize that Google actually REQUIRES developers to list a support email in the app listing. Yes, I'm aware the support can be quite bad and sometimes go unresolved but the only option to get these apps fixed is more customer complaints. I am looking at you Fox and ESPN.
Cheers
What if your issue is with Google itself, who notoriously doesn't have much customer support?
