I was regularly overseas for about 3 months at a time, away from my car. Sometimes I'd find after being away for a longer time, my car would go into a deep sleep and wouldn't initially respond to the app. Once I was back at my car, would go to the car, open it, it would fully wake up, and car would respond to the app like normal. Wouldn't do it every trip, but every so often it would. I'd try that and my guess is everything will go back to normal.
