Signing into Acrobat Sign redirects to Adobe Acrobat

Hello, when a user signs into Acrobat sign with their school account they get redirected to the Adobe Acrobat page, with a listing that they have an Adobe Acrobat Pro subscription. When they open Adobe Acrobat the request signature tool is also greyed out. We have confirmed the account has a enterprise creative cloud license. How can we access the Acrobat Sign Features? Other users in the org have the same licensce with no issues access the Acrobat Sign webpage nor is the request signature button greyed out.
