We are working on an issue reported by multiple customers in regards to Gainsight Assist plugin when gmail’s split pane mode is toggled on.  This is due to an issue at our downstream vendor. Our team is currently working with our vendor on a fix for this, and will share updates on this thread. 
As a temporary workaround, please use the plugin with Gmail split mode turned OFF

 

UPDATE:

We have published the latest build with a fix in chrome store few minutes ago. It usually takes 1-2 days to get the approval from chrome store. Once the build is approved, the issue will be completely resolved. We will update as soon as we get the approval from chrome store.

UPDATE: 

The new version 1.7.3 is available in chrome store now.
