Menmachii , via OnePlus 8 , Oct 25, 2020 : I was able to connect my Haylou GT1 Pro on my OnePlus 8, but it doesn't have sounds. When I'm connecting to my other device (Samsung A50s), it does have sounds. Help please. Note: I just updated phone to OxygenOS11. I think that's the problem. Also, before updating it works perfectly on my OnePlus 8.
