After 2 months of only using PAK it finally failed me.
This morning I no longer could get my phone to connect as PAK. Luckily I have my activity key wrapped in foil hidden in the car. Definitely a bummer hopefully only a short term issue.
In another forum someone mentioned issue with the digital key and customer supports response which solved it for them. I haven't tried it though might help in your case.
Haven’t tried again yet. I will know tomorrow morning. In the meantime I’ve logged out and logged back in to the app and then my next step if it is not working is to re set up everything.
