Heres how it looks in the app.
Tactics stats not loading in app

Tried it and it's still doing the same thing. It's weird because all of the other categories (blitz, rapid, etc.) seem to work okay.

I tried clearing the app data and now it loads the previous problems which is nice. It appears that the app doesn't display how you're doing in the different categories of tactics like sacrifices, mate in 2, back rank, etc. I really like that feature, but I can only seem to view it through the browser. It would be nice if there was a way to view that in the app.

When I check my stats for the tactics trainer in my browser I get all these details about different percentages of different puzzle types I've solved and all these nice graphs and whatnot, but in the android app it doesn't seem to load anything under the tactics trainer. It has one graph that shows my rating progress and even that seems messed up because its just flatlined on one rating as if there is no history. It doesn't even display any previous puzzles. In the stats it loads other stuff such as my blitz games and includes some nice information and diagrams, but I would really like to see my stats for the tactics trainer on the app. Is it supposed to load them on the app too or is it just more dumbed down on there? The tactics trainer is pretty much the main reason I've decided to pay for a membership so this is really irritating.
