Fluent Forms : Ajax submission enable/ disable

I’ve noticed that the option to enable or disable AJAX submission appears to have been removed from Fluent Forms. I reached out to support and was informed that the option is no longer available.

However, this has created an issue for us. We have legacy forms that were originally using AJAX submission, and they are still submitting via AJAX—even though there’s no visible setting to turn it off now. We urgently need to disable it for certain forms but cannot find any control for it anymore.

Was the removal of this option intentional? and Is there a way to disable AJAX submission on a per-form basis now?

This has affected our user experience and needs a quick resolution.
