The message that Viki posted said the app would no longer be "supported". I've also noticed that new episodes and subtitles are still being added. I don't think they changed their mind. But if there are technical problems with the app I'm assuming Viki won't be fixing those problems.
A few weeks ago, because I assumed that the app would no longer work I purchased the Roku streaming stick for my SmartTV.
I'm really glad I went back to Roku, which I used from 2009-2013.. I started using the SmartTV app for Viki in 2013 when we purchased our first SmartTV.
I'm really liking the Roku stick. All watched episodes are noted across all platforms (Viki.com, Viki's Roku, and the Viki app on my android). The Viki app on my SmartTV doesn't do that. So it's great to keep track of what I've watched.
