Facebook Ads Relevance Score | Low Issues

I’m using the same locations US, CA, AU, NZ with lookalike audience 1% interest engaged shopper.

Same ad video, landing page, copy write, etc. and it got a relevance score of 4.

Is this really relevant?? I’ve read about getting small reach when it gets low score.
Is there an Q&A about this? Let me know what you guys think

and how can we increase this score. i barely get relevance score above 5…
