It's definitely worth taking another look.
The Ash DSLs get full autocomplete from your LSP and so make sure this is setup. The new Elixir LSP called Expert - https://expert-lsp.org/ is coming soon and aims to make this a much smoother process.
The documentation has been overhauled multiple times and is constantly being improved. If you encounter issues please raise an issue or a PR, knowing where users get confused is important for improving the docs for everyone.
One issue that new users often run into is that Ash is spread over multiple packages for different extensions and Hex didn't support multiple package search, which is being currently improved. So double check you're searching in the right package. Dash can help with this offline if you have it.
Tidewave (https://tidewave.ai/) MCP can help with doc search too if you are using a LLM/AI assisted editor like Cursor, Windsurf or Claude Code, etc. We also have some Ash specific announcements this week along these lines... ;)
