Hi! I have a similar but not identical issue; I’m able to download the results file, but half the participants’ data is missing. I’m pretty confident that my results file isn’t exceeding the allowed space since only a few participants have been run on this project, and only some didn’t save?
Just sharing here just in case our issues are related!
More detail: I ran 6 people all on the same link, and only the 3rd, 4th, and 5th participants’ data are showing up in the results file. I’m pretty confident that they got to the “results sent to server” page because we were in person and I saw their screens after they were done. In case it’s helpful, the demo link is https://farm.pcibex.net/r/yWGMAU/; everyone was given the same data-collection link instead (let me know if I also need to share that!).
