Cave spawn mechanics work in a way so you likely have 7 monsters in caves within a 4 chunk radius of the slime chunk, not allowing anything to spawn. You would have to dig the whole chunk out, then light a 4 chunk radius of land around that.
Find a surface ravine. If it's a decent size it almost certainly cuts through a slime chunk and I bet you see them spawning on the ravine floor. Due to sky access they count (I guess) as surface spawns and you can avoid the messed up cave-spawn mechanics that Prowl talks about.
It's the only way I was able to farm a bunch of slime balls. Found a ravine with a slime hopping around at the bottom, and hung out there for a couple of in-game days.
You are wrong. Just sit there in your wrongness. :-)
Actually, you kind of have it right - they supposedly spawn most often during the full moon, and supposedly never during new moon. But that only applies to the Swamp Biome spawns. Spawns in slime chunks are not dependent on moon phase. Or they aren't supposed to be.
Technically (according to Wiki), for swamp spawns the game generates a random number between 0 and 1 (say, 0.54) and then if the level of brightness of the moon is greater than that number, there's a 50% chance of a slime spawn.
So obviously when the moon is crescent - light level 0.2 perhaps - it's less likely that the random number will be smaller. When the moon is at brightness 1.0 (100%), it's basically 50% likely that a slime will spawn if other conditions are met (light level, altitude, etc.).
Of course, everybody seems to report that slimes aren't spawning like they should in swamps so the mechanic could be a little broken. I was able to catch a couple in a swamp near my base, but it's nothing like I recall from Console Edition where every night pretty much the swamp would be teeming with slimes. Maybe that version was broken?
To add more, swamp spawn are affected by moon cycle, but in general swamp is not effecient. You'll get a rare spawn on a 3/4 moon, and a couple on a full moon. Swamps are a pain, you need to light up a decent radius around them, light up any blocks above y=70, ideally you fill in atleast some water... those drowned mobs spawn like crazy, and you gotta run around non stop killing regular mobs to keep slimes spawning.
A ravine is the easiest way to get a few quick slimes, slime chunk slimes can spawn day or night, so during day time, with sky access, slimes are the only mob that can spawn.
To make a farm takes a ton of work, digging out the slime chunks you want to I think it's y=40 or so (I'm probably off by a few) but to be the most effecient you want to bring it down close to bedrock, then light up a 4 chunk radius at surface level, and fence it off to keep wandering mobs from coming in.
I built a single slime chunk farm and it works, however if you’re going with illmango’s super productive 1 chunk farm, you’ve majorly screwed up because from my tests i’ve managed to figure out that large and even possibly medium slimes WILL NOT SPAWN with only 2 1/2 space between each spawning platform (1/2=slabs) and I do not know why but I do know that you need 3 1/2 blocks (again slabs) between each spawning platform and this solves my issues.
Did the Bedrock edition change the slime chunks?
According to the Wiki, in Bedrock edition, slime chunks are in the same locations regardless of which world/seed you are in.
I am using Chunkbase, I went to 80,-112 and then dug down to y=35, then dug out from 30-40 on the altitude
Slime are suppose to spawning below level 40
I then dug a tunnel 25 blocks long to afk in, that puts me at the 24-32 range, but nothing spawns
So Chunkbase seems to be wrong, or they changed bedrock to be more random, any suggestions?

I thought I heard something about them only coming out during full moon but I could be wrong.

Had trouble finding them too I just walked about the swamp biome making my maps for a couple nights until I saw one.
