I didn't think this required creating a new thread, but I had wondered why I hadn't received a MyHyundai notification the last few days when I knew I had left my doors unlocked at least twice when I got home from work while I was either taking out or bringing in the garbage cans. I just now tried to open the app and it won't because it says there's an updated version available and it wants to send me to the app store. Needless to say, the app store says the app is no longer compatible with my phone.
I have an Android 9 phone (Moto Z3) and the MyHyundai app had still been working up until now. I guess it's appropriate timing, though, since my 3-yr complimentary Bluelink subscription ends in a couple weeks and I wasn't planning on renewing, even at the discounted rate for which I'm starting to get emails.
