Hi! Can I ask what country are you from? The term adobo is very common in mine, but I’d never eat one with coconut milk! I’d just go with the combination of soy sauce and vinegar.
Unwarranted tip: Add hard boiled eggs when it is almost done, for a more exciting meal!
I am one of those extremely odd and strange people who likes very, very many things across many different cuisines...
...except eggs. Eggs and yellow Summer (or Fortune) squash.
EDIT: Note, I eat plenty of eggs in things. But, when I run into a whole boiled egg sitting in my food, or a fried egg on top of a bowl of bibimbap, I pick it out. Even more odd: I will eat tamagoyaki without a problem.
Filipinos like to make cooking videos on YouTube - if you search "Filipino pork adobo" on there you'll get many. They have a distinctive accent so you'll easily avoid the pretenders. It's a fairly simple dish so it suits the video format.
IMO what went wrong with that first recipe you found is not enough soy sauce and it needs to simmer for much longer.
