The title says it all. Whenever I tap a thread, there's a pop up saying that my Tapatalk API is not valid or something. Tried reinstalling the app, still the same problem.
Currently, Jay, the maker of the app, has been on vacation and currently doesn't have the required equipment to work on the app. He does come back on Monday though, and the app should work after he looks into it. If you're wondering where I got this info, it was posted on another thread and I had to search for it. You're not the only one with the issue, everybody is, so just a little waiting and setting should be back on track!
