If you've added the Prime Badges App Block and see the following message after changing your Shopify theme:
"Update theme in the app dashboard. Go to App → Account → Theme"
it means the app is still linked to your previous theme. You'll need to reconnect Prime to your newly published theme.
How to Resolve the Issue
- Open the Prime Product Badges & Stickers app.
- Navigate to Account.
- Under Theme, select your currently published Shopify theme.
- Click Save.
- Turn the Master Switch Off, then turn it On again.
The app will now reconnect to your active theme, and the Prime Badges App Block should start working normally.
