The simplest explanation is it's the digital age, where unless you do Zoom (or other video calls), the nuance of humour is lost. If you're lucky to establish a brain connection then all should be well.

I have a friend, we've never met in person or by video call. In this case, experience (age and interests) mean that we can indulge in humour that others may find difficult to accept or understand. That's the brain connection.

Sadly and it can't be blamed on mobile phones, texting, etc, I've found people today just don't develop either a sense of humour or understand the finer points of irony or sarcasm.

You're not alone in this. However, it depends on how well you know the people as to whether you indulge in this type of humour or leave it alone. It's called "knowing your audience".
