The top author list doesn’t show the correct number of sales. I’ve over 500 sales less. Anyone else noticed that?
Same here. It should be fixed soon
Yep, same here too. It’s like we went back in time… 
The sales count in top author list is not updated instantly. You can check in right sidebar (below filters) which shows when it was generated.
That’s not the issue. Right now we’re seeing 50+ less sales on all authors across the list - this most certainly not because it hasn’t updated yet - it’s showing less sales than it did yesterday and weeks ago! 
Not on all authors. I personally am not affected. It seems that sales from deleted items have been excluded from the total sales count.
That sounds a lot more plausible. Now we’ll just have to wait for a fix.
