Whitney and Zack’s absence

Not sure if this has been discussed here already but I notice Zack and Whitney distancing themselves more from the bates, including from Carlin and Evan. I know they have a bigger family now so that could be part of the reason why, but Whitney always seemed to have the biggest FOMO so she was always there, and now she seems to just hang out with her kids. I wonder if anything happened or their reasoning for not attending many events or hangouts lately.
