Just received letter from Amex regarding my Blue Business Plus card notifying me of changes to Membership Rewards Program terms & conditions

Effective Nov 1

Temprarily suspend your ability to earn points

Hmmmm, what does this mean?

(not sure if this should be in this forum or manufactured spending)
