Hi there @Salohcin
Thank you so much for your first post to our community forums and welcome to the team! It's great to have you here!
I'm so sorry to hear that you have been facing this issue on both devices. Can I ask if you are able to view these channels on any other devices at all? If so does the message still appear?
Does this only happen on this channel? If not what other channels are effected?
Have you also tried deleting and reinstalling the app?
Thank you.
