Signa S2 Bluetooth auto shut off

Options
Hello - I know it’s pretty widely acknowledged that the auto shut off feature on the signa s2 stinks. But I can’t return it so, here we are.

Does anyone have a workaround though for keeping the speaker on when using Bluetooth?? I’ll play audio from my phone to the bar (something like a radio stream I can’t get on my appletv) and after 15 minutes, it shuts off. It’s like it doesn’t recognize I’m using the Bluetooth.

Help?
