Does Windows 8 break WP7.5 wireless sync?
Seems like it. I upgraded my Windows 7 box to Windows 8 last night. Went well actually, only took 30 minutes. I just noticed that my latest photos from my HTC Titan weren't placed in the camera roll folder, which always happens wirelessly when I charge my phone. Now it won't work.
I tried recreating the wireless sync setting, and then I tried uninstalling Zune and reinstalling. No dice. It syncs fine with the USB cable, but it is supposed to fire up Zune automatically after charging for no more than 10 minutes, and sync. It's not doing that in Windows 8.
I did find this: MS Community Post Am I alone?
