WhatsApp not showing on 1040

For some reason, my 1040 has stopped showing any WhatsApp messages.

I’ve looked at all the settings, it should be working since they get pushed to my Forerunner; the notifications are down to Garmin Connect, not the devices. Other alerts come through, such as email and SMS.

I’m not sure if anyone else has a similar issue, which means it could be due to the latest version, or if anyone has any Ideas?
