if your using any of the RLine products and having issues connecting the DSP, use the Expert Tune app and you'll be able to connect. Expert audio if you see this add a sticker for the QR Code for the expert tune app on your boxes
App works but won't configure channel 5 and 6 in the crossover setting in the app itself ..using S22 ultra.
Can't connect error await Bluetooth connect
worked for 2 months , now bluetooth won't connect. Don't bother with this one
As of 7/17 and after 3 emails and phone call explaining the problem with the app an update became available and the app works flawlessly again thanks
App doesn't load keeps stopping on s22 ultra . It's extremely inconvenient as I needed to tune my car today
The app worked great last year. When I installed the device. Now the app doesn't even open. Is there an updated app ?

A drop after an update usually means the update broke something.
