Thanks for that. Just needed confirmation. Since it is such a new model, I'm now suspicious that there's something corrupt in the OS that likely can't be flushed without a factory reset. I hate recommending this, and it really should be a last step effort. Before that I would try uninstalling any channel that is acting up (Peacock and Philo were the two mentioned), reboot the Roku (critical step, don't skip) then add the channels back in.
It's unlikely a misbehaving channel install would be blocking the OS update, but stranger things have happened. You might also try connecting to a phone hotspot and then checking for an OS update. That has worked with some users that were unable to complete the initial user setup with a new device. Perhaps that might work for the OS update as well.
