When I first turn on my Poly, the P-Status light flashes quickly between Red / Green / Blue, but only after I have added new music to my microSD card. It does not show this behaviour otherwise.
I do not think this relates to Glider’s behaviour.
Glider works best, when using it on-the-go, at the moment, when connected to my iPhone’s shared internet. When trying to use it at home, it is much more erratic, with faulty song counts, frequent loss of connection and often playing other songs than the ones in the display.
