I have the Nokia Lumia 928 for about 2 weeks now and am still in the learning phase. SkyDrive had worked flawlessly until my phone updated and a Beta Nokia app for apps loaded on my phone. Since then I can no longer access my pictures on SkyDrive. I tried to uninstall the Beta Nokia app but all I see is 'Pin to Start.' How can I find out exactly what happened, as opposed to guessing that it is the Nokia Beta app for apps, and reverse whatever was done?
