Thanks for Reaching out to us for your concerns.
We have not removed the zoom tools from the main toolbar and those are already there.
I assume you might have undocked the Toolbar so you may be getting a black floating window over the document area which would be having the zoom tools.
I would request you to kindly Dock it back to the Main toolbar by clicking the rightmost icon from that floating window.
Also, if this is not the case i would request you to kindly do a right click on your main toolbar and select “Reset Toolbar” from the context menu. (This way your main toolbar will get back to the default state which would anyways be having the Zoom tools.
Let me know if this fixes your concern

The magnifying glass zoom tool used to be in the top level of tools, you could select the tool and then use it to draw a marquee around the specific item you wished to zoom in upon. This functionality is missing. I am only able to click the plus (+) and minus (-) to zoom. This is supremely frustrating. Why remove a common tool that users need? And if it's still there why bury it? And that annoying floating overlay black box of tools that appears on the pdf bottom of screen is always in my way (obscuring my view of something), but I cant remove it. This feature is not helpful to professional users who are editing within acrobat. Also, why is the crop tool now so buried? The crop tool also used to be top level, and why did the developers feel the need to change the way its worked for 20+ years? Please return it to the way it functioned just a few years ago. (Not broke, don't "fix" it.)
