Removing a stuck YT Capra dropper seatpost

Maybe I'm dumb, but it took me a while to realize that the internal routing had a bit of an external "bottleneck" near the base of the bike, with rubber joints that need to be moved around in order for the cable housing to slide. It's especially not obvious if you're working from the wrong side if the bike. 😂
In all videos I've seen online, the cable seem to move freely from one end to the other so I didn't understand why mine was "stuck".
If you're in the same situation, hopefully this video will be useful!
