He hasn't fixed it, at least on Android eleven. I just tried the latest version with dig and it didn't work. You can snag an older version that works. Specifically, v3.0.222_(beta)-222. That's what I did.
I've had emails back and too with the developer and he was adamant there was nothing he could do. It's an Android eleven thing, not his issue.
I don't know enough about these things to know why the likes of pizza boy and retroarch can work on eleven.
