Do the Kardashians still talk to Caitlyn?

I'm just curious, do the Kardashians maintain any contact with Caitlyn nowadays? Have they mended their relationship or moved on? I've noticed they don't often mention her in public, but does that necessarily mean they've severed all ties? Could it be a matter of privacy or simply avoiding certain topics? It's always fascinating to see how friendships and relationships evolve in the spotlight, especially within such a high-profile family. Do you have any insight into this?
