Ok, so firstly to your question, it sounds like you aren't happy at the company, not just that they may, or may not be unhappy with your fit. Personally in my experience, managers will only push someone out if they are continuously bad at their job and even then they'll spend months trying to find another solution.

I do agree with others here that you need to sit down and really think about what type of company you want to work for and start there.

It does sound to me that this company has process issues...tickets that are too big for a sprint, manager is micro-managing instead of letting the team self-manage etc. I think the team could do with a bit of space and time to figure out what their flow is. In software development there are those who fit well into a procesa driven culture and there are others who prefer more fluid approaches. You seem like the latter.
