MYGMC App 216 error

[Jmcab]

As of 4 days ago MyGMC app cant connect to my truck. 2019 AT4, had been working perfectly for 2 months on iPhone 8 latest iOS .  I’m currently waiting on star tech to trouble shoot.  I’ve tried all the basics: logging in/out, uninstalling etc. Anyone else have this issue?  Thx.

Can you log into your On Star/My GMC account on a computer? The answer may help lead to the problem.

Hi Jay, good idea. Yes, I’m able to log on via my PC and view vehicle diagnostics. Any other thoughts?  Thx.

Know someone else with a phone you could try the app on? If you can log into account on computer is has to be an issue with the phone/app combo (something on the phone is corrupt). I have had to wipe/reinstall everything on my iPhone a couple of times for issues like this. Make sure you have a good back up before wiping the phone if you decide to try that. Also look at anything installed on the phone recently. Another app could be causing some conflict with the GMC app.

Hi Jay thanks for the suggestions. Tonight my phone updated to IOS 13.1 and I am back in action!  So strange, but thanks for the replies.
