Just got the 2024 Roku Ultra. Loving it so far except for one issue that did not occur on my previous Roku Ultra.
When pushing a button my my remote, to switch to the ROKU input on my TV, the Roku will display the default purple background, and will reboot three times then loads the apps screen.
This Roku is connected by HDMI. I do have the power savings mode on. I'm fairly confident that setting was not enabled prior to getting this new Roku.
