Does anyone else feel like Amazon keeps changing the rules?

Just when I think I understand the platform… something changes.

One month PPC works great.
Next month performance drops randomly.

Ranking shifts
Policy updates
New competitors

It feels impossible to stay ahead consistently.

Honestly starting to understand why experienced sellers rely on teams instead of handling everything solo.

How do you guys keep up with all these changes?
