Umbraco Forms API - async?

We’ve got a headless set up and submitting forms via the Forms API.

This works fine but the submissions are super slow even with just the standard email workflow.

When the email workflow is disabled the form submits much quicker so it’s clearly waiting for the workflow.

There’s a setting in config for summiting async which is marked as ‘experimental’ which doesn’t seem to help.

This is. Umbraco 13.

Anything I’m missing?

Turns out the setting went away in v10.

We did this a different way, built an endpoint which the front end passes the form data to, we then pass back a success to the front end to say we’ve got the data, then we submit the form and the workflows process without the user waiting.

Clearly won’t work in all cases, where we might have return something to the user about a workflow or extra validation, but works for our use case.
