Hi!
Bug report here: I saw the announcement on "Improved Save and Fill", and I decided to try it (the pre-release version, where you have to opt-in, on 19th July 2022). As soon as I turned it on, hotkeys stopped working: I use my asssigned hotkeys for "next/previous credentials" but nothing happens. There's no console output in the chrome devtools. I checked my extension settings and the hotkey assignment was still there, with the correct key mappings. I enabled and disabled this feature a few times and this behaviour is consistent. I use hotkeys a lot, so I disabled the feature.
I'm using ChromeVersion 103.0.5060.114 (Official Build) (arm64) on a MacBook Pro (Apple M1 Pro 2021, 14-inch), macOS Monterey (12.3.1), LastPass free.
Cheers!
