Zwift won't find my Elite Direto - Help?

Hi

I bought an Elite Direto 2, had 5 rides on it now, when I first set it up it connected to Zwift straight away.

Went to use it today and didn’t automatically connect, also didn’t appear when I searched?

The ANT+ in the corner has a warning sign over it? I have no idea what this means.

Can anyone help?

thanks
