Acrobat DC has a different interface than previous versions.
For training, you might try Garrick Chow's Acrobat DC Essential Training on LinkedIn Learning after you look at the tutorials on the Adobe website that Souvik gave you. LinkedIn Learning is a paid site, but you can get a 30-day free trial if you have not subscribed before.
