Nope. One of them was my own. It's more than 24 hours old as well, and then I clicked a random one in the queue and it also did nothing.
I guess I'll try again since some time has elapsed.

It let me upvote another deck this time, but not my own.

Ok so like... Secret Stone can't be upvoted. If I have this issue, others probably have the same issue or similar...

If anyone else is reading this DO NOT upvote the deck (unless you want to), there is probably an actual problem with upvoting somewhere, for some reason.
