In this paper, we generalise the results of Lekili and Polishchuk arXiv:1705.06023 to establish homological mirror symmetry for Deligne--Mumford stacks whose coarse moduli spaces are rings or chains of rational curves joined nodally, and where each irreducible component is allowed to have a generic stabiliser. The mirrors are Z-graded open Riemann surfaces. As an application, we prove the Lekili--Ueda conjecture for invertible polynomials in the case of curves where the grading group on the B--side is allowed to be non-maximal.
