Hi @DennisK1,
Welcome to the Roku Community!
Thanks for letting us know about this. We'd be more than happy to take a closer look at this.
When you updated your credentials on your Netflix, have you tried logging back into your Netflix account on Roku? If so, are you seeing an error message after that?
We also suggest reinstalling the app and performing a system restart from Settings>System>System restart before adding the channel back, then try again to see if it works.
If there's no improvement after doing that, we advise you to contact the channel support team directly about this and what they can suggest.
You can reach Netflix support here: https://help.netflix.com/en/
Let us know how it goes!
Thanks,
Rey
