I hope Apple implements it how they already do with the Back Tap accessibility option. By giving a preset number of system / accessibility features, and then listing the user’s shortcuts library. Otherwise, it would be weirdly restrictive of them.

If you go to your profile tab, click settings > accounts > edit account, delete your password, and type in anything other than you password. Try to save this, and it will fail to log you in. Now renter your real password and it will save your account info. This acts as a “refresh” for you account token.

It’s a bit cumbersome, but there’s currently no way to manage accounts with only one logged in.

EDIT: I stand corrected, the latest TestFlight has added a logout button to the account settings page.

Not OP, but I wouldn’t say there’s any major differences. I did notice they were slightly stiffer when I first installed them, though after a week or so they feel totally smooth. Precision feels the same, definitely not worse.
