CI Supported in the Pop Window Supported
It turns out that if you use notifications to open up messages and try to reply, CI covers the email body window so that when you type, your text gets covered by the CI window. It's impossible to use pop ups and CI together in GMAIL.
Support confirmed that POP UPS are not supported in CI which is unfortunate as we deal in email and rely on notifications to alert of important messages. We can no longer click the notifications to reply, instead have to go back to the main gmail window and reply normally.
Surprised to hear this, with nothing on the roadmap either. Let's bump this up! I can't be the only one!
