iphone app has no audio / PC app unreadable on high-res screen
I installed the Windows app on a Surface Pro 4 running Windows 10. It has a high-resolution screen, which results in a very small app, and no ability to expand its side (without changing the resolution for everything, which is not a usable solution). Is this a known issue? When can I expect a Windows app that can accommodate a high-res screen? (No, hitting the "expand"/full screen button also does not work - the app stays the same size and *does not expand* to fill the screen.)
I also installed the iPhone app on an iPhone 6 (with all patches installed). *It has no audio.* I uninstalled and reinstalled. Still no audio. (Yes, the volume control works for all of my other apps, video and audio, as I expect it to.)
And to top it all off, when I reinstalled my iPhone app, it told me that I had too many devices activated. The only other installation I did was on my tablet (see above). Am I really not allowed to install on a PC and phone at the same time? Come on!
