Insider Rewards Not Showing?

Hello, I just started my Insider "journey" today. A couple of hours ago, I was getting my rewards the second I completed the task. However, they have not been working for the past hour or so. For example, I turned on Dark Mode for the first time, and it still continues to say I haven't unlocked that achievement yet after countless reloads and unlogging out of my account/relogging back in. I've also done my first post, first like, etc... and am not getting credit for them. Any help would be greatly appreciated. Thanks!
