Hi, all. Bought a refurbished 255s music to hopefully upgrade from my 735xt. It arrived today but seems super laggy, per the video. Software now seems to have updated and such but still slow. However, as soon as I turn off Bluetooth on my phone it seems to speed up. I'm therefore wondering ​​​whether this may be temporary whilst some sort of updates, syncs etc take place. It's restarted a couple of times but we're now about 5 hrs in and it still seems laggy whilst connected to phone on Bluetooth.

I'd be most grateful for any insight or tips before I message the seller.

Thank you. ​​​
