Flex is a premium Shopify theme available directly and exclusively from Out of the Sandbox. As such, there is a slightly different process in order to preview the theme that doesn't require going through the Shopify theme store.
Customizations are not retained between a Flex Preview and purchased Flex theme
The Purchase Theme button on the Themes panel on Shopify will NOT complete the purchase of the theme. It can only be purchased via the Theme Updater App or directly from the Out of the Sandbox website.
Install the Theme Updater App
Install the Out of the Sandbox Theme Updater App in your Apps admin. Although the Theme Updater App offers different paid plans, requesting a trial of the theme does not require any paid subscription.
Additional Themes from Out of the Sandbox
Scroll down to Additional themes from Out of the Sandbox.
Click the Try theme button. This will prepare the preview.
A modal popup will appear indicating the theme is installing.
Once the theme trial has finished installing, you will receive a success popup message, where you can then click the Customize theme button to test out all the Flex settings and features or click the Close button.
The theme will be added to your Online Store as a Draft theme. Try out some features and settings here to get a sense of the theme's extents and limitations.
We encourage you to explore all the settings, sections, and features so that you have an idea of everything that's available with this robust and unique theme, and get an idea of how you might want to ultimately configure your shop and flex your creative muscles!
