I am in the same situation. My iPhone connects to my 2020 Ford hotspot for its internet connection. It works fine except for asking pandora to play a different channel or song. The Ford sync 3.4 responds with needs credentials or something along those lines. it is plugged into the sync ports for power.

Hi @mojaux! Thanks for posting your experience to community.
I've moved your post over to a new thread, just in case any one else has a similar experience.
So that I can investigate, could you provide the following information?
Sounds like you're connected via USB based on your description and using voice commands with Ford Sync to switch content. Does the same thing happen if you control Pandora directly through your phone?
Can you do me a favor and please share a picture of the error message that you see on your head unit.
Use your mobile device only when conditions allow and as permitted by applicable law.
The sync screen on the truck pauses the song playing and the Siri voice says new song playing, but then says oops there was an error and goes back to the existing song. The phone responds correctly when out of the vehicle so I probably don't have a setting right on the sync interface. I have to give a thumbs up on the screen taking my eyes of of driving. Truck Is 2020 Ford with sync 3.4 latest version and pandora is latest version for iOS. Phone connects to truck hotspot when traveling. I set up Pandora on my phone when connected to my home wifi and maybe need to install on the sync instead. Thanks for the help.
