Several channels are not working as of yesterday, July 31, 2022.
Disney+: "We're sorry, we're having trouble connecting you to the service. Please check to see that you're still connected to the Internet, and try again. (Error code 42)
HBOMax: "Sorry, but we were unable to authenticate your device and can't continue"
ABC: "There appears to be a problem. Please try relaunching the app. If you still experience issues, please contact us at abc.com/roku Code 013-0600-406"
This is on Roku Ultra. Channels have been removed, the device rebooted, and the channels reinstalled. Still no luck. The Roku is connected via ethernet and I can confirm the internet connectivity with a laptop connected to that cable is fine.
Multiple channels/apps not working points to something in your network connection, but what that is won't be easy to figure out. If you have another network that you can connect to like a friend's or the hotspot on your phone you could maybe prove that it's not the device itself.
