Abstract
The proof of Lemma 5 in de Frutos et al. (J Sci Comput 80: 1330–1368, 2019) is not correct. An alternative statement of Lemma 5 and its proof is provided. With this new statement the order of convergence of the pressure is reduced by one half order in the spatial mesh size. Changes in the results relying Lemma 5 are also provided.
