I have a Samsung galaxy A54 and a watch4. Whenever I get a WhatsApp message, it gets delivered to the watch, but the watch doesn't vibrate or flash up when I get it. So I am not aware that a message has arrived. I've done all the troubleshooting tips like checked notifications are on for WhatsApp and see to vibrate. It's been sent off to Samsung but they found no issue with it. Anyone else had this problem?
