Only two valid devices show at browser roku.com and they are correct
however, when I go to the app there are other devices listed that I want removed
they were from vacations and will NEVER be used again
i can find no way to delete them
I have this same problem...
Thanks for the notes here. Try uninstalling the Roku mobile app, restart your phone, then add the app back again. This should clear any record of previous devices that you've connected to.
