Ignoring the typical challenges around Auth, 2FA, etc. Is anyone having success getting these out of "demo" stage and actually deployed with any scale?

I keep running into the same issues. Same prompt, same website, same input data, different results on screen (missed a click, wasn't focused on the right thing, flubbed the EU cookie modal, etc).

So I'm looking to poll the community here. Has anyone gotten this reliable to a point where they deploy it into the cloud and it runs without a human babysitter? If so, can you share some of your approach with us?
