This is unfortunately an issue that Google/Android introduced with an Android update. We are looking into it, but it seems that google need to fix it in a future update.
@hifime Is there any update? It still pops after the latest Android update. The product is not usable. How do I get a refund? I purchased this through Massdrop.
It might work with USB Audio player pro, or the Hiby app. Or you can set it in Airplane mode (wifi on) then it is also reported to work.
As you bought it from Massdrop then you'd have to contact them regarding refund.
You can return it to us for an exchange to another product or a store credit, however we can't refund you if you didn't buy it from us. Please contact us directly to arrange it:
