Hey, PM at Microsoft here. I have used this often, and I find it to be perfectly suited for quick mockups and testing new ideas. However, it is still a preview, so there may be cases where live apps may fail on the device. Be sure to let us know, we are eager to improve this product!
Hey! I work on the Xamarin team at Microsoft, and I would like to help out on this! Are you able to send me the crash logs or application output? Thanks!
