It started four or five days ago, but I didn't think anything of it because it has happened before. Normally if I restart the phone or I delete and re-download the app, Live Tiles start working again. However, this time none of those tricks seem to be working. This time it's also not just one app, it's all the apps that aren't Microsoft built. It's not the end of the world, but kind of annoying. I'm not on insider builds and my OS version is: 10.0.10586.164. Has anyone else experienced this or have any suggestions on a possible solution?
