Can't save a chess game

[sjl872964789]

Describe the bug First of all, thank you for developing this amazing application. I always failed to save the chess game before. After trying, I found that I had to open the stored permission first. Can you ask for the permission or at least prompt the user for the required permission when using this function

Device: [galaxy a6s] OS version: [Android 8.1.0] App version: [2.5.9]

Steps to reproduce the behavior Download and open gobandroid Start a chess game Save chess
