Just a quick heads up to tell you that we've released Briefcase v1.14.0-beta.0 with a new "resume last pull" feature that we need help testing 
The new feature will save time and resources by skipping all the instanceID batches that have already been pulled. In a form with 10 000 submissions that means saving 100 HTTP requests and checking 10 000 submissions in the local instance database.
More details at the usual places:
If there's no major issue with the release, we will be releasing it next week.
