Whether it fits is settled first. Whether it is worth buying is a separate label.

What looks like it fits iPad Pro (M4) but does not
Buying the wrong size is the most common error, followed by an older Magic Keyboard: the M4 version is a separate product and the previous one does not attach correctly.
These sit in the same stylus aisle and are confirmed for a different exact model. We have no published answer saying any of them fits iPad Pro (M4), so treat them as unverified for this device rather than as a fit.

Coming from an older model
Why a previous-generation stylu may fail here
The M4 iPad Pro is thinner than the model it replaced and moves the front camera to the landscape edge. The 11-inch and 13-inch sizes are separate fits and always have been.
Nothing from the previous iPad Pro fits: the thinner body changes case geometry and the Magic Keyboard is a different part.
