You should be able to play it after finishing day 7, unless you pressed skip! Make sure you have the most updated version as well!
I redownloaded just in case and I still have the issue. It asks me to continue then goes straight to night 8. Also, night 8's background isn't loading properly either. Not sure if that's part of the issue or not. Thank you for helping!
I'm on Android too and night seven isn't working no matter what I try
