As long as Settings->Touch & Pedal Settings->Enter Annotation Mode with Stylus Input is enabled, the hover event should trigger it. If you have enabled air actions or some other feature for the stylus in the main tablet settings, it's possible it's interfering with the hover events. or perhaps there is another setting that could impact hover events. You may have to dig through the settings to see if something has changed. If you have air actions on, turn those off and see if that fixes the issue.
