We're completing your digital order

I recently purchased a Supercruise plan, and the app froze up during the purchase. I got a receipt email, and tech support was able to get my plan working in the vehicle. Since this purchase the app has a banner at the top that says "We're completing your digital order. Once it's processed, you'll be able to place a new one. Please refresh". The icons to add anything to your cart, such as an Onstar plan are also gone, so I can not make any purchases. This has been like this since June 5th. I've logged out and back in, deleted and redownloaded the app, and tried logging in from a PC, and have the same result. Has anybody experienced this and fixed it? I've had enough of sitting on the phone with them just to get my plan working in the first place.

Thanks
