I don't know, but it's a good question.
What I can tell you is that the Steem blockchain is working, because if you look at stuff with a blockchain explorer, everything is posting normally in real time.
Could be more of the same as when Amazon Web Services made the site a bit dodgy, four days back.
I guess the only thing I can do is to wait till tomorrow. Thank you @denmarkguy.
From looking at it a bit further, I think they may be rebuilding some database, or something. When I first came across your post, the newest transaction I could see in my wallet was 15 days old. Then it was 11. Now I can see transactions from five days ago.
The main concern is whether any transfers are going astray, as you may have experienced.
Yes, the history keeps changing in my wallet, I didn’t send much today, but still curious what happened to it.
