If you, like me, started to recently get the error “This item cannot be shared. Please select a different item” when sharing to Whatsapp, then this might help you.

You are probably sharing a text-item. In my case it was a text containing an URL.

Instead, I now share the NSURL-object (or an array of objects, in which one is an NSURL object).

I am relatively sure this is a bug in the latest version of Whatsapp, but as long as it persists, this might be a workable workaround.
