I am sorry to hear that. I don’t personally use Android Auto, so that’s a situation I’m not familiar with. I am also sorry to see people downvoting your comment just because you report a bad experience, that doesn’t help anyone.

I would recommend opening an issue about it on the project page in GitHub. Another advantage of FOSS apps is that developers are usually easer to reach for feedback and support, although I must say I don’t have experience with the AntennaPod developers.
