I can't use Android Auto in my Landrover as the infotainment system is too old, I would have to get a newer car as you can't upgrade the infotainment system so not an option. I connect my phone to it via Bluetooth set for Audio and Video so my phone runs through the infotainment system and all the car controls work with the phone, just not the phones screen. Might be an option for you until the issue is resolved
I have a 2019 seat ibiza my ultra s23 works fine with aa disconnects now and again but that's on par with aa anyway, wired as mine doesn't support wireless
