"Press The 1Password Icon In Your Browser’s Toolbar To Unlock"

After a recent update, I get "Press The 1Password Icon In Your Browser’s Toolbar To Unlock" for every attempt to use 1password in the browser when 1password desktop app is open. When I investigate, I see "Integration status: Connection problem" on the app's settings page. 

I see that this is a frequently occurring problem. I've tried some of the suggested fixes and am having no luck. Not sure where to go from here.
