Not only this, and I don't know whether this is happening to anyone else, but once or twice every week, I can't open a game in an MLB.tv app on any platform unless I reauthenticate my Extra Innings credentials yet again. That's new starting this year. Didn't have that problem in prior years.
As for the Carplay app, I don't bother. If it's a home game, I listen to the Tigers feed on my Sirius in the car; if it's an away game, I will either run the Tigers feed through the At Bat app if it's working, and if it's not, open it in the Sirius app.
