I often put my phone on my wireless charger while I work. It sits there playing music.
This is why I like the new now bar, as I can expand it and it shows me the album art fully.
However, it doesn't always work. Most of the time I expand the now bar, then put it on the wireless charger, and it works. But sometimes, it doesn't stay expanded on the wireless charger.
This is strange, because I never have this with a wired charger. Does anyone else have this, and is there a fix for it?
