It has been 72 hours already and no new messages. 

In addition, everytime I try to access the modem's details through the chat assistant, it does nothing as if there's no redirect available. 

I was also told today by a technician that this is an ongoing issue and affecting every customer. Can you please confirm or provide an explanation as to what's happening? Thank you!

Thank you for clarifying further what you are experiencing, user_eyrjyg. I am not seeing this as a known issue being worked on by our engineers. We will get to the bottom of this!
