How does a paying customer get help with product bugs?

Thanks for the reply, I’ve been hoping to get get help here as well. The forum is a bit problematic when it comes to choosing proper categories or tags (some of which are rejected/can’t post with a specific tag selected).
I’ve posted the issue in this forum: Colors from a library updated in inspector but not design which probably isn’t the best place to post the topic, but I was unable to find/select more fitting category/tags.
