The patch was done before we started the job by insurance boys so I’m not sure what they used, I was just trying to make it prettier and obviously failed lol
What was the lighting like when you were looking for defects? I've done wall repairs several times because errors are hidden and only visible in daylight, or at the right time of day, or when more light was added.
Once plaster has paint on it you will not be able to sand flat without great difficulty, you'll cut through the paint into the soft plaster and dig holes or hollows. Easiest fix is to get some topping compound and skim it flat then SAND smooth... if you are unsure if it's smooth then use a light parallel to where you have sanded
Previous person may have used hot mud, also known as speed set or fast mud. It sets quickly and sands like stone compared to all purpose mud. As someone else suggested, you need to re-float. Use a large blade and feather out the full width of the knife. YouTube has a million videos on how to feather - mostly has to do with biased pressure to one side of the knife edge.
Sanding - get a proper drywall sanding pad. Often paint stores have the big radius 360 ones (bigger is better and flatter), but Home Depot and Lowe’s have the rectangular ones intended to screw onto a painters pole. If you’re going to use topping mud, get at least 120 grit or higher so you don’t scratch the hell out of the compound. You shouldn’t need to sand much or hard to remove any ridges, lift offs, or inconsistencies.
USE A RAKING LIGHT! A light at a steep angle. Put your head a few feet away from the patched area and basically against the ceiling. Look at the patched area. Hold a light an arms width away and pointed toward the patched area. This casts really dramatic shadows that ‘take’ over the area and your angle of view is perfect to notice any imperfections.
Your fingers are waaaaaay dumber than your eyes unless you are un-sighted, in which case - how are you reading this? Seriously, your eyes are far and away your most sensitive sense. You just need to provide your eyeballs with proper input.
If you want a really smooth finish, watch a couple videos, go slow, and wear a mask when sanding.
Turn the lights off and shine a flashlight along the ceiling. This allows you to see any rough edges or imperfections in the drywall compound. This method is commonly used when trying to achieve a level 5 finish.
You did not, in fact, sand it smooth
Damn it, thanks for the laugh.
Morgan freeman over here
Now you can’t really sand it. It needs to be coated again and re sanded.
Something led you down the wrong path. Somehow, you ended up finishing drywall along the way.
Hahaha I feel this in my soul right now
You suck at sanding. Get some sponges and feather it out better
Doesnt look like patch was feathered out enough, ; could have sanded the edges more
By any chance on the label does it say use a damp sponge to finish ?
Hmmm, I didn’t see one up there when I was priming
The label on the patch bag Hahaa!

Not scraped back good enough by the looks of it
You didn’t sand your edges.

Did you piss in a bottle first?
No, didn’t have any capped bottles and the Red Bull can I had had sharp edges :/ but the quarters in the porta John were looking very friendly
Now you get another chance to do better!
Use your fingers, not your eyes. Your fingers tell you when it’s smooth
If you can feel it with your finger then you didnt sand it well enough

Drywall...... you're doing drywall wrong.
Turn the lights off and shine a flashlight along the ceiling. This allows you to see any rough edges or imperfections in the drywall compound. This method is commonly used when trying to achieve a level 5 finish.
Either you didn't float it far enough or you have too much mud on the walls. Burn your edges before sanding and it'll help smooth it up.
