I am not sure what you are asking exactly or how to answer. I am confused.

Someone else answered that it's caused by different relays.
That doesn't make sense, because you have a common relay with primal in amethyst, and it's primal's own relay.
That implies that anything you post in amethyst should appear in primal.🤔
What I post on amethyst does appear on primal. However, what I posted on Primal through web browser does not appear on amethyst. 🧐
