Hi there,
This is something I have also experienced and is something that we are looking into (see similar thread here: How to trouble shoot when online experiment gets stuck only for few participants - #2 by Becca for a couple of points that might help with debugging).
As far as we are aware there isn’t a data limit from our side of things, so I suspect this is a browser cache/memory issue. Some things I would be curious to know:
- Does it happen everytime?
- Does it happen if you clear your browser cache before running the study?
- Does it happen on several devices? (I found the issue in my experiment on phones but not laptops).
- Does it happen across several browsers.
You’ve correctly identified that splitting in 2 might be the solution for now - but it would be good to avoid this if we can!
