Failure to send forms that were saved in old version after revisions

[LN]

This looks like the same issue as discussed in this thread:

Update filled in and saved form, but not yet sent

Apologies for the delay in getting back to you about this. Unfortunately, there's not a great answer for this right now. Were you able to resolve the issue? Some options: Get another device side by side and re-enter the data in the other one. Get the data off of the device using these instructions and then manually push the submission using the API (or Briefcase) Use a text editor to edit the raw submission and change the form version Let me know if you'd like more details on any of those.

Like I wrote in that thread, it would be helpful to understand your form testing process. Did you use the draft test? Is this constraint maybe on a field that's not very commonly seen so it wasn't part of your testing process?
