Why am I not able to copy and paste descriptions for properties?
Can you give me a bit more detail about where you're seeing that issue? You should be able to copy/paste anywhere. We don't have buttons for that because browser security limitations don't allow us, but you can copy/paste by Ctrl+C/Ctrl+V using the keyboard, right clicking and using the menu, or tapping and holding if you're on mobile.
Do any of those methods work for you?
