Hi, I told here on one of my posts that my filters change alone...I choose one and my wiim pro plus changes it for the first one in the list of six. It's annoying. I discover that if I let the app on background, it almost doesn't happen. Can you check your wiim to see if it happens to you too??? My wiim has only 10 days of unboxing. I hope it is not a hardware issue. The music sounds amazingly good. Thank u.
