The issue affects all Out of the Sandbox themes except for Artisan.
A recent change on the Shopify platform has caused the Back in Stock Notification forms to stop working. The form appears to be sent successfully but it does not actually send the request for notification to merchants.
We have updated our themes to resolve the issue with the form. The Back in Stock notification forms are working as expected in the latest versions of our themes:
- Turbo 6.1.0
- Flex 2.0.8
- Parallax 4.0.4
- Retina 4.7.6
- Responsive 7.2.6
- Mobilia 6.2.5
