Two things:

1) There is no more link in the Adobe Benefits section - all it says is adobe.com - and this text - NO LINK, no button, just Adobe:
Enroll and get up to $150 in statement credits per year for eligible annual prepaid business plan purchases with Adobe on Creative Cloud for teams or Acrobat Pro DC with e-sign for teams on your Business Platinum Card.‡*

*Annual prepaid business plans automatically renew each year on your annual subscription date until cancelled.
‡Benefit Terms
Business Platinum Adobe Benefit

Only the Basic Card Member or Authorized Account Manager(s) on a Business Platinum CardŽ Account can enroll the Card Account in the benefit. Eligible purchases must be charged to the enrolled Card Account for the benefit to apply. Purchases by both the enrolled Basic Card Member and Employee Card Members on the enrolled Card Account are eligible for statement credits. However, each Card Account is only eligible for up to $150 per calendar year in statement credits. Valid only on purchases of annual prepaid business subscriptions for Creative Cloud All Apps or Single Apps for Teams or Acrobat Pro DC with E-Sign or advanced E-Sign for Teams. Adobe Creative Cloud InCopy App is not eligible. Individual and Student & Teacher plans are not eligible. Annual prepaid plans automatically renew each year on your annual subscription date until cancelled. Purchases must be made directly with Adobe where Adobe is the merchant of record for the purchase. Please allow 6-8 weeks after an eligible purchase is charged to your Card Account for statement credit(s) to be posted to the Account. Please call the number on the back of the Card if statement credits have not posted after 8 weeks from the date of purchase. Note that American Express may not receive information about your eligible purchase from merchant until all items from your eligible purchase have been provided/shipped by merchant. Statement credit may be reversed if the eligible purchase is returned/cancelled. If American Express does not receive information that identifies your transaction as eligible for the benefit, you will not receive the statement credit. For example, your transaction will not be eligible if it is not made directly with the merchant. In addition, in most cases, you may not receive the statement credit if your transaction is made with an electronic wallet or through a third party or if the merchant uses a mobile or wireless card reader to process it. To be eligible for this benefit, Card Account(s) must be not canceled and not past due at the time of statement credits fulfillment. For additional information, call the number on the back of your Card.

2) There is a 25% back on Adobe as well, so I think you can double dip!
