I have achieved full automation! Well, nothing is ever 100% automated, but all of the major processes are now automated. One of the ways I launched quickly was to punt the things I didn't know how to do and some of the edge cases. Instead, I just did them manually. There were several backend FTP processes that I could not figure out. Thankfully, a friend helped me through the details and it is now automated! This frees up my time to focus on growth and product improvements. It also means I could mostly walk away from it and have it grow organically as a source of passive income. Whew! What a weight off my shoulders.
Looking back, I think I would do it the same way again. Get the happy path working, get it in front of customers quickly, don't be afraid of manual processes, but then come back and automate it quickly.
