Unable to open WhatsApp notifications on my Apple Watch

Hi there,

is it normal I can receive my WhatsApp notifications on my Apple Watch, but I can't OPEN it to see the full message, and possibly reply etc ...

All I can for the moment is receive the "resume" (first few words) of the WhatsApp message, nothing more. When I click on it on the watch, nothing happens ...

Many Thanks !
