same here, My bluetooth will work fine after first connection. but when I wake the phone, bluetooth setting showing its connection, but there is no sound. I have to disconnect the bluetooth and reconnect the bluetooth to get my sound back, but I find myself doing that several times to get my sound back. Normally I have to disconnect and reconnect several times for my Airpod pro to work, and for galaxy buds need two cycle to get it work. need update on this Apple!!!
