Revert back to the classic UI. This is hands down the WORST version of Acrobat ever!
Ax the leadership that thought it would be a good idea to change a well established tool causing myself and so many others so much frustration and wasted time that I am motivate to post this nasty-gram.
Please publish a public statement and apology for making such a brash and disruptive change. I would be happy to personally berate the troglodyte(s) responsible for this offence personally!
