I have checked this but I have still needed to sign in to iPlayer. None of the other apps. Just iPlayer. Kids get frustrated the most as it is stopping them watch their programmes.
Any other ideas?
I had everything unplugged a few days ago when I replaced my stand and didn't need to sign in again to iPlayer.
You could try a factory reset if you haven't already tried that, go to Settings > System > Factory Reset
It's only a partial system reset and not a complete factory reset. You are given 2 options,
Choose Keep Recordings, that means you won't lose your recordings and any planned recordings or series links you've set up, but you will have to sign into all your apps such as iPlayer, Prime, Netflix and ITV Hub again, also Match frame rate and Standby power consumption will go back to their default settings if you have changed them.
