My Shopify store is built on an older version of the Minimal Theme. I have two questions. Here's my website: www.questionnaires.com
1. The Social Sharing Image displays incorrectly. When I share my website on Facebook, the logo is blown up and cropped. It’s displaying the website logo, which is long and narrow, and cropping it square. I want it to display another version of the logo, in a square format.
2. I’m still running the older version of Minimal because I had a lot of product customization done. There are 4 Tabs, and custom templates that display questionaries. If I upgrade, all the customizations would have to be rebuilt. A Shopify guru told me that if I continue to use the old theme, one day, my shop will stop working. True?
