Prior to the upgrade Acorn worked fine. My ROKU automatically upgrades all channels so one day I turned it on and noticed a major format change. No problem, I watched two shows Problemthe shows were never recorded in my recently watched list. To watch additional episodes I had to go back to search and find the shows. Emailed Acorn and their response was upgrade the Acorn channel on your ROKU. That is what caused the problem. I suspect all Acorn users now have a beta version of the software. They should de-bug before implementing a new version. Emailed them again telling them their fix didnt work. Will see if I get a response.
