Not quite sure how it works for Android, sorry. Hopefully someone else can help. You can try asking in Harem Hotel's community discord.
The last time the game was running on version 0.12.4 [PC] on an android emulator before the broken Joiplay update appeared. When I replaced the game version with 0.13 (without Joiplay update), the game would not start anymore - as if the Joiplay update was required (although faulty). Now when I try to start the game normally on PC without using the emulator, trying to load saves crashes. The new game starts up seamlessly. I was playing on the emulator because I have no memory on my phone.
