I got the new Samsung Galaxy 4 classic watch a couple of weeks ago and for 7 days straight notifications didn't work! I have tried all of the troubleshooting multiple times, I have had the Esim reset twice by EE, I've even had my watch replaced thinking it was a faulty one but guess what? It does exactly the same with the new one! So, I must be doing something wrong somewhere or my phone has something that Is blocking it.
I am using the Samsung galaxy note 20, it worked absolutely fine with my old Samsung galaxy watch active 2.
Any ideas or solutions please because it seems I have exhausted all troubleshooting on the Internet.
