I wonder if no one has asked it simply because it is so obvious, but I really can't grasp the exact meaning of there you have it (again). I occasionally infer it from the context but not every single time.
Here are some examples:
1 There you have it again: a baseless assumption that some undefined external “force” has a mind of its own, and the faint but menacing suggestion that anyone who disagrees is in some fashion opposed to the holy or paternal will.
2 There you have it again. He’s realising again how deeply he cares about her and he doesn’t know what to do with these feelings. He’s lost her twice and he fears to lose her again that’s why he’s afraid to acknowledge that he does feel something for her.
3 There you have it again – the same company, the same city and a very similar incidence.
4 If you missed the news, there you have it again.
Oxford Learner's Dictionaries state that:
So, there you have it means that's how it all started.
Can I assume that the above phrase (without again) applies to all the examples I've given?
Thank you.
