I have switched plan to get Premiere Pro and lost Acrobat Pro, why not can I have both?

You can also have separate plans to Premiere Pro and Acrobat. If you don't see both, one possibility is that you may have two Adobe IDs. If you have two Adobe IDs, you would have to sign in with each one to see items stored in the Cloud.

If you have two Adobe IDs, contact Customer Care to combine the accounts. Do not respond to PMs.
