Thanks for reaching out. You may want to make sure your subs have selected 'Include creator posts' under the bell settings for your channel. Note that Community posts always appear on the Community tab, and may appear in Home or the Subscriptions feed. Keep us in loop.
We understand. You could mention it in your videos, about turning those settings on. We'd also suggest getting in touch with our Creator Support team: https://goo.gl/BxLi8H . They'll dive into this further with you. Thanks.
