One thing to note with that argument is the request can timeout if you set it too high for your hosting environment.
It’s also worth noting that the latest Gravity Forms version updated the bulk permanently delete entries action on the Forms list page in the admin to use the background processor to delete them in smaller batches to reduce the risk of timeouts.
It was pretty quick, and it didn’t timeout on my setup for the 5000ish entries of my main form.
Still, my ultimate goal here, is to clear all the entries, from all forms, when moving my live database to local, or preparing to share it with someone else who just shouldn’t get these data.
So being able to target all the forms at once would be even better!
Does it make sense to you? Or maybe you have another approach to suggest?
Thanks for your reactivness by the way, very appreaciated
