Yep.

iPadOS 27 broke many keyboard use cases for me, including very simple things like using tab to move to the next field on a form in Safari. It worked in iPadOS 26, but doesn’t now.

This adds to the bug where switching between apps with modifier keys tends to cause those modifiers to “stick”. That bug has been there for years, and prevents me from using my iPad as a programming environment even though the software support is there.
