Hi bib and welcome,
I've had issues with EA chargers too, but not that issue stopping the charger prematurely. I too had the charger locked to the car, at 1AM on a Saturday morning without charging and the charge controller screen prompting me to remove the connector and reinsert it but it was locked to the vehicle. 3 times to unlock with the fab worked. There's also an emergency unlock cable in case the electronic release solenoid fails. However, if drawing a charge, there's a risk of "Arc Flash" in resorting to the charge connector Emergency Unlock. For me, calling EA and learning about the 3x unlock was more helpful than VW Roadside Assistance.
Your experience with the charge controller stopping prior to the set level is odd. Glad to see you were able to come up with a solution on your own and on the spot. Let us know if you can duplicate the problem. I opened a can of worming with my first post about cost to charge at DC Fast Chargers. When you connect to a DCFC the EV communicates via "Handshake" and sets the maximum allowable charge rate for the ID.4 at 125Kwh. This sets the billable rate at, in PA at least, at $0.32/min. Even though your max charge rate recieved was 62Kw, when the free charging is exhausted in 3 years we'll pay twice what we should have at $0.16/min the Tier 1 DCFC rate (1-90Kw limit). Someone posted that once you drop below the 90Kw charge rate it re-calculates from $0.32/min to $0.16/min. That's not true, the Tier 2 $0.32/min rate is established at the time of the "Handshake" regardless of what actual Kw rate you receive.
Now for my unqualified answer and based on my experience, I think the ID.4's setting in the infotainment center is what determines the desired SOC and not the EA App. There are some other things that occur during the "Handshake" such as current State of Charge (SOC) in addition to the battery's State of Health (SOH).
Also, check under the Vehicle tab in the infotainment Center and then go to the Locations tab and either erase the location or change as needed.
