What engine problem are you talking about?
It won't work correctly on my android device since android 11 came out
Renpy engine was updated so it can be fixed in next version of the game. Or not, because I have 11 android and it's worked perfect on my phone (0.6.5F)
Did you have any issues at all and if so how do you fix it?
On my device I don't have any issues. It's engine problem, main developer of renpy engine try to fix it at this moment. So we just wait
