I tried to charge my Model 3 LR at our local supermarket- Tesco offers 15 min of complimentary charging via 7 KWh chargers paired with Podpoint. When I tried to make use of this opportunity I found that though the charger recognised the podpoint source it could not charge and an error message came up stating "no power source detected" but this was a functioning EV charger and I saw other EVs being charged. Have other users faced this and do I need to change something in settings to enable non TESLA chargers to charge? I use Podpoint Home Charging with no problems.
