Why is Samsung Pay not available on S22 Ultra?

Hi, i bought the Samsung S22 Ultra recently. What benefits do i get with this phone? When I got the ZFlip 3, I got 6 months of free youtube premium. Now I can see there is a Spotify premium offer but only for 3 months. 

My Note 10 plus had loads of vibration patterns but the new ZFlip 3 only has a few. How is that?

I have the ZFlip 3. After signing into my Galaxy account, my previously downloaded themes and AODs to do not appear under 'My stuff'. Is there a way to retrieve them?

Since the latest security update (July 2021), the battery on my phone is reducing at quite a fast rate. I have to charge it multiple times now, even though my consumption is not much. Has anyone else had this issue? If so, what can be done? Thanks
