• click the 'Switch account' button on the page that opens (why? it already knows that's what i want to do):

btw: clicking 'Authorize' on this page works fine to authorize the extension with the old account, so the bug is after this.

• login on the webpage (google or email, doesn't matter):

it just drops you at https://claude.ai/new. it completely forgets that it's supposed to authenticate the plugin.

to continue you have to go through the manual code copy/paste.
