Just saw a YouTube short pointing out the "mistake" of Dedra Meero claiming to have been raised in an "Imperial" kinderblock, despite being old enough to have lived through the fall of the Republic. Unlike Dedra, the Galactic Empire isn't old enough to buy revnog and peezos. So what gives?
The thing is, plenty of characters in Andor refer to the late Republic as "Imperial" in the present day of the story. For example, on Ferrix we hear that Kenari was the site of an "Imperial" mining disaster. But in Cassian's flashback, the mining disaster has clearly already happened - yet Maarva refers to the approaching threat of a Republic warship.
These inconsistencies aren't mistakes - they're worldbuilding. It illustrates that to people in the world, the distinction between the late Republic and the Empire has started to blur. Imperialism extends its influence not only in the spatial realm of planets and sectors, but also in the very minds of its subjects. Additionally, it mirrors something from the Prequels - by the end of Attack of the Clones, when we see Stormtrooper-like Clones boarding proto-Star Destroyers as the Jedi Council looks on, we are meant to understand that the Republic-Imperial transition is already well on its way.
The fact that Andor understands this, builds on it and communicates it to the viewer without banging us over the head with exposition-laden dialogue is just one example of why it's the best piece of Star Wars media produced... maybe ever? And the fact that this is lost on the Star Wars Content-Industrial Complex is disappointing, if not unexpected.
