Gmail Chrome Extension can't login anymore

[Anonymous]

Hasn't worked since a month ago, and nothing has been fixed.

If I open extention, there is just a white window. It seems data can't be loaded or rendered:

If I click on Hubspot's icon in Gmail UI, it shows Log In window. After succesful login procedure it's still shows Log in window:

I tried:

1. Update Chrome
2. Update Extention
3. Re-install Extention
4. Clean Google and Hubspot cookies
5. Remove 3rd party Hubspot access to Google
6. Remove integration with Gmail in Hubspot settings

Hi @Anonymous,

There is a very comprehensive article on troubleshooting the extension in the knowledge base. 

It looks like you have already gone through a lot of steps. 

Are you using any third party extensions that could potentially be conflicting with the Chrome extension?

Have you checked if there are any conflicting advanced setting as mentioned in the article?

Best,

Jess
