I perform a manual system update daily to force updates to my Roku device as it can sometimes take a while for system & app updates to automatically reach all devices. Most people just wait until they get the automatic update, especially as updates can sometimes get pulled if there are bugs identified during the auto update period.
1-touch play no longer seems to function correctly. Was fine with previous version. Has trouble waking up TV once device has turned off after 4 hours (auto power savings). Once you have manually selected correct HDMI input it functions correctly again for a while.
