If you don't have the latest version of Acrobat installed on your computer, choose one of the following options in the browser prompt:

For Individual and SMB plans, Document Cloud Review Service will no longer be displayed to end users on the Your plan page under account information. The functionality offered by this service is to send documents for review, which is already included in your Acrobat product. As a result, there is no impact on the “send for review” access for end users and how they use this feature.
For Enterprise plans, Document Cloud Review Service will no longer be displayed in the Products Detail section on the Adobe admin console. Its functionality is also included in "PDF services", making it a redundant service. Admins can continue to leverage “PDF services” in the Adobe Admin Console to maintain control of send-for-review access for their end users.
