I've had various issues with maintained settings (unexpected theme changes after software updates, Channel Guide updates that restore previously hidden channels). Tonight, I just experienced the Roku TCL 4K HDR TV update 12.0 debacle and had to perform a factory reset to get any semblance of usabilty and QAM channels restored (the * button failed to work to get to "all hidden channels; only pay channels listed, etc.). I thought the -exact- same thing - my customized settings should be saved so they can be restored when -you-, the provider, royally mess things up for customers who have a reasonable expectation that the device they paid for will function satisfactorily... I now have to re-login to the the various streaming services I have subscribed to, and now need to step through and again 'hide' all of the (what I perceive to be "pointless"/not of interest channels in the "live TV" streamed channel listing, so I don't have to scroll through pages of listed channels I will -never- view...
Really, I have better things to do with my time -- don't you also?
