I created a private study for openings and I have 18 chapters that are very densely annotated. I'm having problems exploring the study now for some reason--Only this study. My other studies work fine. In all browsers, for some reason, just this one study is extremely slow and does not work right. There's an echo where I make a move and I hear two move sounds one right after the other. Sometimes certain moves I can't even make, it just takes them back. It's very strange. I tried opening the study in every type of browser, one at a time, refreshing my internet, even tried it on several different machines with all the same problem. What's going on?
