If you don't see a new field you just need to keep the miniExtensions app in Airtable open in the sidebar to keep it in sync.
We recommend using our new extension on the Airtable Marketplace. It doesn't require installing a separate app for syncing because it lives inside Airtable.
On the legacy site app.miniExtensions.com
You need to sync your base every time you make changes to a field/view/table. You would need to go to Airtable and open the Sync App or run the sync script manually (if you have installed the scripting app).
You only need to install the sync app once. You don't need to install it multiple times within the same base. Only one app is needed to connect between an Airtable base and miniExtensions, regardless of how many extensions are being used. If you already have the Sync App installed more than once, you can safely delete the extra apps and keep only 1. This won't have any effects on the miniExtensions connection.
Common Error: Could not load data because the following field does not have all the required schema values: Try re-syncing your base.
