It’s happening way less than before. It has actually only happened once, since making this thread.
I’ve attached screenshots. More as proof, than anything else. They don’t solve the problem.
But, I do have one observation to add this time. I updated the firmware on my Airport Extreme.
Infuse found all the media just fine after the update.
But I had to reboot the phone to get the airplay function to work (see screenshots).
*So I have half a theory… if that’s a thing…?
If the “source” (my airport extreme) is turned off and then on again at a later time, it can sometimes cause something to happen with Infuse.
Although, - yesterday it happened again, and the Airport Extreme had not been turned off.
Youtube can still airplay, when Infuse can’t. So I don’t think it’s the phone or the router (Airport Extreme)?
I hope this is useful.
*my theory was debunked after I tried replicating it, and then the error happened “out of the blue” the other day.
