I also have been waiting for a Chrome Store approval the past few days. And also can confirm that updates are usually very fast. One theory - they're A:B testing/training an LLM-based approval process & taking extra time to write extensive feedback/validations for their AI. Or they're between tools. I think it's very likely that LLMs will end up doing this review. (They already likely had an algorithm to detect whether anything meaningfully changed etc for version increments.)
