I haven't done any systematic testing, but I think I've observed that sometimes my iPad Mini 6 benefits from a reboot.

This has happened about 4 times, most recently after I returned home from 2 weeks in Poland.

Each time I've noticed that the music sounds less engaging than usual, lacking the usual magic.

First time, I tried rebooting Källa, but that had no effect.

I then rebooted the iPad and that seemed to bring an immediate benefit.

Each time now that I've felt the magic is missing, I reboot the iPad and the magic returns.

This seems to happen roughly every 2-3 weeks. Between the reboots the iPad spends most of its time on charge. I only use it for Spotify or Radio Paradise.

Has anyone else experienced this?

I can not confirm. So far the IPAD has run through to the bitter end a few times due to the Sagatun upgrade. A restart didn't show any improvement. However, I only use the IPAD as a control point for the Källa.

I think this was my imagination.

No restart since my first post above and no loss of magic.
