the Tumblr app is making me crazy

The Tumblr app has notifications, usually only "So-and-so liked your photo", but sometimes the notification starts differently but then I can't find out what it wanted me to inform about, because when I tap on the notification, it only opens my dash, and when I go on to check account activity nothing shows there either.

I just clicked on a Tumblr notification on my tablet that had popped up without really reading the excerpt, except noting that it wasn't the standard like/reblog thing, but now I have no idea what it was, because there is nothing new in the inbox or the account activity of either of my two Tumblrs, and of course the notification goes away once you tapped it. Argh.
