Good to hear you weren't intentionally being disrespectful to other members. We want to help you figure this out without making assumptions and sticking to the best facts we can get our hands on.
I'm gonna beat a dead horse, though: If your tank was cycled and stable, you wouldn't have wild parameter swings. And with test strips, you aren't able to get decent readings in order to adequately (or as adequately as we can get as everyday hobbyists) measure the ammonia, nitrite and nitrate levels as your system works its way through the nitrogen cycle. Unfortunately, you/we can't be certain your tank is "cycled" as it stands.
Let's take this a step further: What's the exact amount of food you added to your tank on a regular basis and what's the measurement of ammonia it produced for you? How many hours did it take for that amount of ammonia to get processed by the tank?
You need to be able to know without doubt that your tank can process a fixed amount (that you can measure - typically in parts per million) of ammonia within a certain amount of time. It has to consistently do that on a daily basis, if not faster. While Neos are hardy in shrimp terms, they're not tough like Endlers or Guppies would be in poor water conditions. That's why it's important to know instead of just guessing or making assumptions.
As another member pointed out, frequent shrimp molts point to water parameters. Possibly KH/GH and/or your tank not being cycled. In my experience, I can say that hardness issues wouldn't result in such quick and repeated deaths.
You said this is your first shrimp tank, so it is absolutely understandable that things aren't working for you like they would for more hardy critters. I say it frequently but use the search function on the forum. It works better than random websites and gives you information from hobbyists who document how they reach a particular conclusion.
Rather than dismiss what experienced shrimp keepers are telling you, it may be a good idea try out some of our suggestions. Get your hands on a quality liquid test kit and let's start verifying these things. If you don't want to, that's up to you. We just want to help.
In the meantime, keep doing water changes or temporarily re-home the shrimp. In an ideal world, you'd be able to move them to a bucket with a filter that has sufficient media from a running and cycled tank until your tank is stable enough for them.
A note about missing shrimp bodies: They're either hidden under something, jumping out of the tank, getting quickly eaten by snails/other shrimp or they're stuck in your filter. If you have your filter intake covered, they're probably just getting quickly eaten by your other livestock and that's a good thing. Snails are beasts and their clean-up skills are why I always keep them in my shrimp tanks.

I noticed 2 bodies before and now another 2 today. I really have no idea what is causing them to die off. I use tap but I declorinate it, levels seem good now, but they are still dying. It just really sucks seeing 100+ dollars worth of shrimp die and not knowing why 😬
I can't get the quote to pop back up for the first one and it won't let me delete my post and fix it.
