I've been using virtual run on my phone with no issues the last few days, but the screen is a bit small to really see what's going on. I'm at the gym, so there isn't an option to cast to a TV. I thought about bringing my windows 10 tablet, and it seems to work great... For a couple minutes. All the stats drop and I assume I lose the connection. Is it because my phone is nearby and the watch prefers it, or is the Bluetooth casting not holding to the tablet? Seems to drop consistently after a couple minutes. No issues with Android.
