On Android 10.2, I saved during the start of Layla's sex scene, went back to it and had a Sasha scene afterwards that gave me a key. I used the key and had a scene that locked me in where I couldn't go back or even use the menu button (if it's a bug, so be it, hopefully it's easily fixed; if it's intended, it's really frustrating being locked in like that, extra so given the other issues afterwards). Accidentally progressed too many scenes and in trying to go back and use menu, I went ahead even further. Being too far forward and unable to do anything, I closed it and was automatically started where I was. Unable to do anything else, I pressed on quickly until I could use the menu, though going so quickly it seemed to crash the game closed. I went to the menu this time, loaded my Layla save mentioned before and it's somehow saved that I've seen the seen that gives the key and after the Layla scene it goes straight into Sasha's next scene where I have to learn second hand about what I didn't get to see. Now I'm stuck with seemingly no way of seeing what I missed (to clarify, I kissed the scene after going into the white door upstairs in the restuarant/home for the first time).
Hopefully that's not too difficult to understand.
