@jimmy691, the only workaround is to connect a separate Roku device to your Roku TV. If that TV doesn't have the horsepower to run Apple's (Roku didn't create the channel/app) bloated code then there's nothing anyone outside of Apple can do about it.
The resolution should be, Sharp & Roku both should have resolved this issue by now. Why haven't they offer customers a free Roku stick or issued an update is just bad customer relations. This is a good reason not to buy a tv that uses a primary streaming service platform like Roku, Google or Amazon. My suggestion is not to buying a tv with Roku, Google, or Amazon as the primary platform on the tv. Your next tv should say works with those streaming apps, So you don't get stuck with a Sharp Roku Tv that doesn't come with one of the top rated streaming services like Apple TV.
Make it right Roku, fit this issue by offering a free Roku stick to your customers. You know my address, I'll be waiting, but until then I will never recommend Roku to friends and family.
@AMO2023 If you want apple TV you, should buy an Apple TV device. I do not know how many years Apple supports it's TV devices though. Perhaps, apple might send you a new device for free when your current Apple TV is no longer getting updates.
