There should be a strong thread running through the shows, but it's not all going to line up "quite" perfectly. Too many episodes, too many writers over too much time. You shouldn't get too wound up.
I can hand wave most continuity issues, but it would be better not to have them.
Or allow enough open-endedness to let viewers connect the dots. It's risky taking a 3 minute bit of dialogue from a show or movie and turning that into a 2 hour movie, such as "Rogue One", which was admittedly fun and decent but still made new plot holes in a series that has an intentional episodic numbering system. Or "Solo", which took a 3 second bit of dialogue and made that a big part of a movie, as well as reintroducing one-off villains with possible intent to keep using them. (That also runs the risk of "small universe syndrome" (SUS), but Darth Maul is gray-area and cool enough, but the more characters they do runs the risk of SUS that much more. Some characters not being fleshed out keeps some mystique, though for others there's a lot of genuine opportunity, especially if screen time is virtually nil, there is room for creative flexibility... On the other hand, demystifying every event and character can be a sign of franchise rot too, especially if there's no depth to the new character...
Ultimately, it's whatever the viewer wants to see or not.
Heck, even if there is continuity violation, some scenes in of themselves are still cool and there's enough leeway in some that it doesn't bother me, but it can for some. It's just too big a franchise and the only time someone really started out with a solid plan, the show got nixed during the middle of season 4 and "Babylon 5" had to scurry to close as many plot themes, only to get revived at the last minute and that rushed feel really showed... Bestor's ending was a bit underwhelming after all that build-up... (Nope, not Star Wars - it wasn't ever "Episode 4" until a re-release, and even the love triangle issue wasn't really sorted out, since the really big continuity problem of Leia telling Luke how she always knew he was her sister but, oops, she's getting all Jerry Springer incesty on him... "oops..." or "eww...", depending on your point of view... or both... but if anyone wanted a better reason why having some continuity set early on and not deviating without good reason, Star Wars' example is one of the better ones...)
