Welcome to the Roku Community, @SIETECH85!
Thanks for reaching out. We'd be happy to help you contact the right support for this.
Since this is a channel authentication issue, we highly recommend coordinating with the channel providers themselves, as they manage and maintain their apps on the Roku streaming platform independently.
You may reach them here: Max Support
We hope this will get sorted out soon and we appreciate the troubleshooting steps you've taken so far.
Best regards,
Carly
