App still works fine (and is up to date on newer functions) on Android smartphones, but is SEVERELY behind on functions added over the past couple years when run on a Shield TV device. Additionally, I found that on 3/21/2022, that the app kept kicked me out of it only seconds after starting it up on BOTH of my Shield TVs (having to resort to authenticating my primary account in the SmartTV Client for Twitch app as a workaround to the clearly busted official app on these devices until Twitch can fix this one). I am giving a 4 star rating on the app when used on my Samsung Galaxy S9/S6, however 1 star currently on Shield TV devices due to it currently being broken on those media devices (normally I would give 2 stars on a Shield TV, stars deducted for missing functions that are available not only over PC web browsers, but also over Smartphones through this app), averaging my marked score at 2 until it's working on Shield TVs again.
