I can’t save – ARia's Legacy - AR Escape Room Review

I can’t seem to save my game. At first I thought it saved automatically, so I closed the app and turned off my phone. When I came back to it, I had to start all over again. Okay, fine, I didn’t get that far the first time anyway. I couldn’t find a save button. Pressing on the top left button just said “if you leave now, your game won’t be saved.” Does the game save after I reach a certain checkpoint? I played for a little longer but found no way of saving the game so I just quit. But I’d love to continue playing if I can! Please tell me how to save.
