The planes of satellite galaxies problem which is that satellite galaxies for the three large galaxies for which the can be detected so far (the Milky Way, the Andromeda Galaxy (M31), and Centaurus A) have a preferred orbital plane and this did NOT seem likely in the Λ-CDM model (see review by Pawlowski 2018). However, computer simulations have now shown that such planes of satellite galaxies though uncommon should occur with a frequency of order a few percent (Samuel et al. 2020). So, unless observed planes of satellite galaxies prove to be much more common that a few percent, the planes of satellite galaxies problem has evaporated and does NOT provide evidence against the the Λ-CDM model.
