Due to an issue with our activity page (what you see when you click the lightning bolt icon at the top right of your dashboard on the web, then click “See everything”), some users are not seeing all their notes fully reported there at the moment.
Our engineers are working on a fix, and we wanted to make it clear that it’s only a reporting issue with the activity page and no notes have been lost from your posts.
We’ll update this announcement when we get more news on a fix for this. Sorry for our blunder—and thank you for being awesome and continuing to use Tumblr!
Update, 11/23/17: This issue's fixed and you should now see your activity graph looking as expected. Thanks again for your patience. ❤️
