Apps will not open in 2021 Silverado Trail Boss LT shows connection error

Hello
Thank you for reaching back out to me. I in fact was able to have it fixed this morning at  the dealer, turns out the are 2 recalls on this for the radio to update the software.
However, I have spoken to 6 different Onstar Reps who all gave me 6 different answers on what the issue was.
the first after doing all the painstaking trouble shooting, that is would be escalated to tier 2 support who would give me a call back in 3 days. Never happend.

The second told me to wait 3 hours after resetting everything that is should work after. The third one stated that it would not work till my 3 months vacation free trail was ended it wouldn't work, so I had them cancel that and started paying for the service, still did not work. ( I want 3 month credit)
The 4th rep stated that unless I had the new google service I would not be able to have access to apps. ( needs more training) I didn't even waste my time with this rep.
The fifth rep sounded like she was mad at the world and hated her job. told something similar to the 4th and even stated a supervisor gave her documentation of this fact ( Not true)

And the 6ths and final rep told me that my vehicle was not capable having the on board apps. ( complete lies) as I have the original sticker which clearly states is does. at least she was partly correct in the fact that I needed to go to the dealer to have them download the apps. except they only needed to upgrade the software and I down loaded the apps myself.

All in all I will say, you guys need to do a better job in providing a better customer experience and train your Reps to understand your system and how it works. This is how companies loose customer.
