Jade plant looks the same for 2 years.
I got a Jade plant two years ago.
It is smallish- two branches coming from the base, and at the top of each branch a handful of leaves.
In the 2 years I have owned it, it has not grown one iota. It is as if it is stuck in time. I let it live outdoors once summer- nothing.
I repotted it- nothing.
It likes to pretend it is going to finally give up and die but loosing most of it's leaves, then it regrows the leaves and stays the same for another few months.
The only thing it does is drop and regrow leaves. Never more leaves than before, never a new branch, never taller, nada.
It's had full sun, low sun, fertilizer, etc.
