I just tried a few operations like staking and claiming, and they all seemed to go through. However, after I accepted the claim operation, the spinner on the site kept going, however the claim did go through, so it could just be a temporary site issue.

After refreshing the page, I was greeted with: You have no rewards to claim.

I also tried a few staking ops, and they seemed to go through just fine as well, including the popup notification...
