Are multiple Chromium instances on single Mac supported?

Hi @jacob1p, thanks for letting us know about this.

1Password does indeed support running the extension in multiple browsers. What you've encountered here is a bug that was first reported a few weeks ago, and which we're working to address - my apologies for any inconvenience this has caused you!

Additionally, I can confirm that Wavebox is a supported browser, and that that's not the source of the issue.

I have added you to our list of affected customers. Our developers are looking into this and we'll hope to have more for you soon. Thanks again, and well look forward to providing updates on this ASAP.
