I bought a mini 4 pro yesterday. It was manufactured on 2023/11. The software is 01.00.0200. Can I use it without any updates? If I can, what advantages does it provide me? What disadvantages does it cause?
Yes that'll be totally fine
The bugs in that version are few and fairly minor / inconsequential.
However, DJI did add a few features since then which are very useful - most notably the ability to look through obstacle avoidance cameras in a secondary screen insert, and, very recently, a whole flight simulator !
Advantages are dependent on your local flight rules at time of manufacture. For example, my Mini4P had remote ID but it is not enabled initially in the UK - likewise we can override the 400 ft altitude limit in earlier firmwares, which may not be the case with later updates. And, depending on where and when it was bought no-fly zones may or not be enforced by the app, which again, may have changed since then.
