There is definitely a storyline going on if follow the cutscenes and pay attention to the map. Ever in the earliest seasons they were doing map-based story telling. For example, trucks showed up and started moving shards to one of the towns on the coast. Random updates would move the trucks. Many plot elements develop this way over time.

The core plot is asking "Why are we stuck in this loop?" It does get convoluted, but it's there.

Various agencies are involved, the Zero Point (which causes the looping behavior) has manifested as many things over the seasons. Aliens and inter dimensional being seek after it.

Maybe you had to be there, but the first batch of seasons and even chapter 2 had many online theorizing and trying to guess what's next.

It's like a digital Lost.
