I have two identical model TCL HDTVs. I noticed on one of them it updated to the latest Roku firmware 14.1.4 on 12/12/2024 while the other TV is still stuck on 14.0.1 11/11/2024. I performed a manual update several times and it still does not see the new firmware and both have strong Wi-Fi connections. Does Roku use serial numbers to update their firmware by batches or what ?
