If you are linked with your spouse and they have more points, you will see their total points to ensure both of you can achieve the next tier together. Once linked, the higher point total in the relationship will be shown.
For example, if member A has 55 points and member B has 80 points, individually, member A is an Emerald member, and member B is a Diamond member. However, if member A and member B link their accounts, member A would then have 80 “relationship” points and Diamond tier as well.
