My notficiations are appearing late. It's been like this for a while. When someone joins my parties, the notification doesn't appear till like a minute later. When someone messages me, it's appeared a whole 2 minutes later. My achievments even sometimes take a while to appear. I've tweeted Xbox Support on twitter and they've been trying to help. They've already had me re-download my profile onto my Xbox One console, that didn't work. Then they asked me my networl statistics, and they seem fine, but my wireless strength is at 80% and they asked me to try to move it closer so it'll be above 80% but I don't know if that changes anything. But it's a good strength.
Any suggestions? Has anyone else been through this problem? How can I fix this? Any help would be greatly appreciated.
