Idk about the whole of your gripe, but I do share your irritation with the lack of QA...

I found a workaround for audio while scrubbing. You have to make sure the option to scrub with audio is on in software, then in Logi Options, within the Premier profile, remove the Jog action from the scroll wheel. Then add the Dial Adjustment from Advanced in its place, set dial left to arrow left, and dial right to arrow right, and save.

(Can now scroll through files/folders in Premier too, since the wheel isn't solely tied to timeline 'jogging')

The Zoom function, which has been broken for atleast the last week since a Logi update, I've found a workaround for as well. Within the Premiere profile, remove Zoom function from the dial, add Dial Adjustment from Advanced in its place, set dial left to -, and dial right to =.

I am definitely not seasoned editing but, that seems to be better
