Hi, im performing a set of simulations on an subsonic elliptical airfoil and ive noted that the only residual that is not reaching the desired tolerance is the continuity one, it never goes below 1e-3? can there be a reason for it, does it means that the simulation setup is wrong?

I think it is nice to stop other solvers and let the continuity solver work lonely. Then see if it converges very well or not. If again it did not converge well, you need to check your mesh quality.

See below for guidelines on converging a solution:

Ok; abut the mesh quality I am focusing on three indicators, this are element quality, aspect ratio and element skewness, besides my mesh is elliptical and structured, so ill try to check that continuiti solver.
