Whereas Web AppBuilder allowed app authors to configure preset values and users could choose whether to use those within the Smart Editor widget in WABs, editing is now configured with Forms and Templates in Web Maps which are then recognized within the Edit Widgets in Experience Builder or Instant Apps.
My organization primarily houses our own data, so we're working with non-hosted data instead of hosted data. Previously, we could preset values for users to optionally utilize while adding features to layers. Now, because Templates only work with hosted feature layers, we are unable to replicate the workflows we've used for years as we migrate beyond WABs.
Big bummer! It would be great if Templates, or any solution, allowed us to achieve the same workflows as we have historically.
