Hey, in the previous version of my mod the button was on the game screen after visiting the house, I don't see a problem doing it that way for people like you, however you made me interested in this QM for phones, can you show me or send me the file where you made the changes? Maybe you did something wrong and just need to change it to make it work, if not I will make the option on the game screen.
I have no way to test the mobile version.
ps. In the attachment you have a version for you, the button in the lower right corner after visiting the main room of the house(down arrow in the room with the bed)
