You'll see this banner on the app home page:

Your storefront data needs restoring — Your indexed products are safe, but the
data the widget reads is missing from your store.
What's happened
Your knowledge bases live in the app. For the widget to render, a copy of that data
has to be published into your Shopify store, and the two can come apart. The usual
cause is uninstalling and reinstalling the app, which clears the published copy
while leaving your knowledge bases alone.
What you'll notice is the widget disappearing from product pages that still say
Indexed.
What to do
Click Restore storefront data.
It re-publishes what the app already has. It doesn't use any AI generations, because
nothing is being regenerated, so it can't change your answers or overwrite your hand
edits.
After it runs
You'll get a count of how many products were restored. It might also report some as
skipped:

N could not be restored — those products have most likely been deleted from your
store.
That's expected. The app is still holding a knowledge base for a product that no
longer exists in Shopify, so there's nowhere to publish it to. Remove those rows
from the Products list to tidy up.
If it fails
The banner will tell you. Try again — it's safe to run as many times as you like. If
it keeps failing, email support@aruslabs.co with your store domain.
