Can't use dexnav features

I can’t wonder trade at all. I’d understand if it waited for a little bit, but as soon as I select the Wonder Trade option in the dexnav, it immediately says “Your wonder trade has timed out”.

I can’t use other features like trading or battling anyone either.

If you can’t Wonder Trade it’s probably because no one else is Wonder Trading. If that’s not the problem have you made sure you’re on the latest version of 1.2.3? If that’s not it, it might just br that the servers have some problems right now.
