every now and again I get the message power supply issues. It did it with my old iPhone 6s Plus and now doing it with my iPhone Xs max. I have tried different cables including the official Audi one and genuine apple ones and it still comes up now and again. Is it these big phones and the MMI can’t handle the lower required? Happens maybe once or twice a week and I either have to restart MMI or unplug for a while and plug it back in. Anyone else getting this?
