My problem is same with you. I bought my samsung galaxy watch active 2 days ago and it can’t give pop up on my watch when there is a whatsapp call like regular phone call. I’m using Samsung Galaxy Note 9. However when my watch is pairing with iPhone it can perform properly and give pop up too when I get whatsapp call. How come it can work with the iPhone but it can not work with his family Samsung. I’m so struggling about this and very dissapointed bought Samsung Galaxy Watch Active. Please share solutions anyone of you guys if you already found the solutions to fix it. Thank you so much. Cheers.
