The Minimalist template in ArcGIS Instant Apps will be deprecated in the ArcGIS Online Oct 2022 update and the ArcGIS Enterprise 11.1 release.
Existing apps created from the ArcGIS Instant Apps Minimalist template will continue to work once it is deprecated, and you can still edit the app configuration. Minimalist will be removed from the Create tab of the ArcGIS Instant Apps home page.
Once Minimalist is deprecated, new functionality won’t be added to the app, nor will reported issues or bugs be fixed.
Recommendation
We recommend users choose the Sidebar template when creating apps for the same purpose as Minimalist.
You can use the Sidebar template to create an app to showcase a map with a side panel that includes a legend, item description, and pop-up information. Sidebar has a very similar configuration experience as Minimalist, plus more optional capabilities, such as editing, custom theme settings, and so on.
