Hi there,
Hope you are doing well and thanks for sharing your detailed feedback.
I completely understand how frustrating it must be to face these usability limitations when using Acrobat on an iPad with an external keyboard, mouse, and monitor. You’re absolutely right that many people now rely on iPads as their primary computer, and smooth support for external devices is an important part of that experience.
At present, Acrobat on iPad is optimized mainly for touch and Apple Pencil interactions, so some functionality with external peripherals may not behave as expected. That said, your use case is valid, and feedback like this is critical in helping our teams understand and prioritize improvements.
I’ll make sure this gets passed along to the product team. In the meantime, if you’d like, you can also share this feedback directly with our development team here https://adobe.ly/425rHxe
