I've been working on an XE8 FireMonkey project for weeks now using my stock Sony Experia Z3C running Android 5.0.1, and noticed yesterday that there was a system update to 5.1.1 available for my phone which I happily installed. Unfortunately that was the end of my ability to compile to the phone, as XE8 does not recognize my phone any longer, no matter what I try. Has anyone else experienced this or can you offer some advice? I've confirmed that USB debugging and Stay awake in the Developer options is enabled.
