The board does not appear after there was an update of the interface. It’s not visible on my tablet and also phone.
Edit: Not trying to bump the post, just updating it as I find out more about the bug. There are problems on desktop too: when you click on Puzzle Settings or Puzzle Collections, there’s no visual feedback anymore (“Correct/Incorrect” or any on-screen text) when you place a stone, just the sound. It has been a while since I visited the puzzle section, so is this just the result of some bugs of this newly implemented UI?
