VWG email regarding new way to communicate with your car

Today I received an email informing me that CA was to use a new more reliable way to communicate with my Skoda Elroq.

The email stated I need do nothing. I plugged the car in as usual and the car began smart charging immediately something is never used to do (at 5pm anyway), after about 6% charge had been added I noticed the charge had stopped and I checked in the CA App. The App said the car was not plugged in!

I tried unplugging and plugging in again, no change. The car and the Skoda App both agreed the car was plugged in.

So the question is, was I just unlucky or is this something to do with the new more reliable method of communication. The previous method of communication has worked flawlessly for 14 months.

As I need the car fully charged tommorow I had to go and do a DC charge.
