3rd party app development support

Hello Onyx team.

Thank you for being generous with your time supporting all of us.

I'm developing a 3rd party education app for BOOX devices. I'm facing technical issues and I don't get reply to my questions in the Git repository (e.g https://github.com/onyx-intl/OnyxAndroidDemo/issues/119 and few more).

Where else can I find help?
