I love these puzzles. So relaxing. But I find that when coming back to the app it doesn’t remember which puzzle I’ve done and I have to repeat each puzzle two or three times before I can move to the next. BORING! At first I thought it might be because I didn’t have an internet connection, but I usually have WiFi. I usually shut down the app between sessions because it uses up a lot of battery. Is that why? Any workaround?
