Has anyone seen instances of Samsung Pay clearing out registered cards?

I have a Pixel 2 XL and a Gear S3. Within the last 60 days, Samsung Pay has begun erasing the registered cards. If I re-register the cards, they will eventually be deleted. If I register yet again, they'll eventually be deleted again.

I don't appear to be the only one with this issue:

Anyone else seeing this?

Any ideas?

Is Samsung aware of this issue?
