Shazam / Music recognition on Apple Watch

In December 2024 I upgraded to a Series 10 watch, since then I've been having problems syncing my Apple Watch to my Shazam account. I'm using the new Shazam / Music Recognition app on my Apple Watch but none of the songs which have been recognised by my watch are appearing on my iPhone Shazam app (I never had an issue syncing with my Watch and Iphone Shazam app on my previous watch). The 'History' section on the Shazam Apple Watch app is not updating. Is anyone else experiencing similar issues and any solutions? Many thanks!

I've tried the following (multiple times) but none have worked:

(1) Updating to latest iOS on iPhone and Watch;

(2) Downloading and reinstalling the Shazam app on iPhone and Watch;

(3) Unpairing and pairing again the iPhone and Watch;

(4) Doing a Factory Reset of my Watch
