I have the exact same issue -- two emails for two different companies, and a unique Hubspot instance for each. I run everything through Chrome and have the Hubspot email extension downloaded and turned on, but it appears I can only run ONE email extension at a time. This means if I’m running the Hubspot extension for email 1 and switch to email 2 to track something in the CRM, I have to manually log out of Hubspot and log back in. It’s frustrating and confusing me! Can anyone help me come up w/ a workaround?
Maybe just run an incognito Chrome browser for one of the emails / Hubspot accounts?
