I've converted our teams CI/CD to use github actions (from mostly running on AWS) at a large company since early in the beta, but we have also run into a lot of issues. Where can I report these issues and get a real answer? I don't mind getting told that a certain feature is on the backburner, I just want to know that someone has considered it.

The best place to report issues or request features is https://github.community/. The Product and Support teams both visit that regularly.

Y'all might be better served by just throwing out a chunk of what you have. When my customer said they wanted to have automated deployments of their webapp to AWS (where branch name = subdomain.dev.customer.com) it took me waaay too long to set it up. It seemed like a lot of your docs would provide examples that were already outdated based on the product being in beta. I assume they're still wrong though because I wrapped up the project 2 days before you left beta and I remember thinking "holy crap, they were that close to being live and the docs were still that bad?"
