Ever since the Browser extension updated, Bitwarden keeps logging me out despite the fact that Vault Timeout Action is set to Lock. This seems to exclusively happen when Vault Timeout is set to On System Lock.
Chrome Version: 83.0.4103.61
Brave Version: 1.9.72 Chromium: 81.0.4044.138
Bitwarden Version: 1.44.1
I can reproduce this too
I can reproduce this as well, with the addition that my vault timeout is set to 15 minutes. Vault Timeout Action is set to Lock. It appears that it doesn't matter what the timeout or action is set to, it always logs out.
Same versions as author.
Hello, below is my configuration, I can also confirm that the browser extension keeps on logging out, and I need to enter my master password whenever I open the extension. (Same Chrome and extension versions as the OP)

Reproducable for me, too. Quite annoying right now.

Thanks everyone. This is being investigated/fixed asap.
I was having this issue as well, but I seem to have found a possible workaround for now:
After toggling it to "Log Out" and back to "Lock" again it appears that the setting took this time and it just locks instead of logging me out all the way.
Since I did the workaround above it has successfully only locked instead of logging out twice. I would be interested to know if others can use workaround successfully also.

Aha, seems to work! Thanks :)
@Zeustopher 's workaround is working! :)

If you cannot log into Bitwarden Chrome Extension, or it keeps logging out, then you can try this solution. Make sure the Extensions Jigsaw icon is visible on your URL. Click the jigsaw, select Bitwarden Extension, then select PIN Icon to toolbar. For some reason, you can't access this PIN function in the Windows/Extension area. Seems like a pain in the behind. Select the new Bitwarden pinned icon, then you can log in .
I set mine to never log out, and selected PIN Code to login, and used my screen saver as the lock out for security (set for 3 minutes) . if someone steals my computer, they can't copy and decrypt the bitwarden file as its encrypted.
