Hai JT20,
The SLP Gravity Forms Plugin has been reenabled again.
You could find the free version in the WordPress repository (see https://nl.wordpress.org/plugins/slp-gravity-forms-locations/).
The premium version can be ordered via the Freemius site.
If you have any issues, please let me know.
On the other hand, reading your request, I wonder whether you would benefit much from this add-on. Its main purpose is to aid creating new stores using the Gravity Forms.
You might be looking for another add-on for Gravity Forms.
Another solution might be to add a new link to each store leading to a dedicated form that has the store ID, name or email as hidden parameter to ease manually following up actions. Or you might add the stores as a selection parameter to the form which enables the visitors to choose the store themselves.
Hope this helps.
Best regards,
DeBAAT
