Hi everyone, I saw that version 2.13 supports PICO 4 Pro and Ultra, and I also saw reports of people encountering a gray screen issue, which I'm experiencing as well. Therefore, I'll continue using the older version (2.9; I recall the issues with PICO started with version 2.10). I know OpenBrush isn't available on the PICO store in mainland China, so I'm also installing it from the APK file downloaded from GitHub. I don't want to add to your stress. I'm just wondering if this issue could be due to differences in system versions between the mainland China version and the global version of PICO?
