Yeah when my Vizio TV would no longer install a few of the streaming apps due to version stuff I just got an external device.
Though recently the TV has been popping up with "No Internet" errors while watching something even though it definitely has Internet. They really do make things to be throwaway these days
I wish smart TVs had a "dumb mode" which disabled all the smart stuff and just ran off the inputs that you could switch to when they stop supporting the TV.
