When I work with themes in Shopify I usually make a copy of the currently active theme, make modifications to the copy, test/verify and then publish the new version. This give me sort of a history and the possibility to rollback if there is a problem.
My understanding is that when installing Algolia and clicking the “Install to a new theme” button in the Algolia Shopify app, Algolia injects files and code into a theme as well as registers the name (or id) of that theme for future reference. The name of the theme is displayed in the “Active Installation” section of the Algolia app. When changing the configuration (store configuration and search options) the changes are written to the algolia_config.js.liquid file in the registered theme.
Now to my problem. I have not found any way to change the “Active installation”, why there is no way to use my workflow described earlier. If I click the waste basket, the algolia stuff is removed from the theme. If I try to “Install to a new theme” using my copied theme (where Algolia already is installed), the app hangs(!)
Is there a way to change the active theme? If not, maybe it should be added?
