In our upcoming deployment window (1:00AM - 3:00AM ET Thursday, February 2, 2023) we will be making the following update to Incomplete Forms and Web Apps.
Currently, Incomplete Forms are always enabled for Web Apps, regardless of whether they have actually been enabled for an application. This means that it is currently impossible to disable Incomplete Forms for Web Apps. We are updating this behavior so that Incomplete Forms are only enabled on Web Apps if at least one application in the project space has enabled Incomplete Forms.
If your project uses Web Apps, and if you rely on Incomplete Forms, make sure that the latest released version of one of your applications has "Incomplete Forms" enabled before the deploy window. See Advanced Application Settings for more details.
If you have any questions or concerns about this change kindly write to us at firstname.lastname@example.org.
Edit: This was previously announced to be released on January 26th, 2023. The release window has been pushed back to February 2nd, 2023.
