Still waiting for mentor feedback, 30days now - Kotlin track

Hi,
I really like your site and learn a lot from using it.
I understand this is a volunteer-based project and really appreciate the work.
I was wondering what would be considered an acceptable time to wait for mentor feedback?

Last I posted here when it was 21 days but now it is 30 days I have posted a solution
and have not gotten any kind of reply.
I would like to go on but do not want to loos the valuable molter input.

My Ex is found at:
