Hi,
I already purchased the basic plan for starting my online shopping portal.
But Still my website display a banner in bottom with the message ‘Enjoy 3 months of Shopify for $1/month - Start your FREE TRIAL’.
So, How can i remove it? We are about to launch our website very soon.
Hope you understand my query and answer me accordingly.
Regards
Do you use Ella theme ?
Yes, I am using Ella Theme. Fortunately I found solution few hours ago.
Are you User of Ella theme?
Yes , please share with me your knowledge 
Where you able to figure how to remove this popup? I also have Ella Theme and this is now showing up on my website.
Was able to figure it out. You have to remove it in your Theme setting. Go into “Theme”. Then “Customize”. Then go to Theme Setting. Then go into the Sticky Notification Bar. Then uncheck “Show on Desktop” and “Show on Mobile”. Then Save. This will remove the Shopify popup.
The sollotion mentioned above is correct as I just removed it my self also
