I just tested it, and managed to get it to work after couple of errors,
as lesson learned, when importing the parent survey data, in step 4; appropriately naming the linked parent project is a must, this mentioned in the article but I didn’t notice it first when I read it,
Overall, this is very useful feature, thanks for putting the time and implementing it.
I’m going to test it, with pre/post-test survey (importing the pretest score to the post-test) to make the analysis easier,
In addition, I am thinking about using the count to prevent duplication in the ID by connecting the survey to itself, but this is tricky as data collectors need to constantly update the survey, and even if done, duplication may still happens because of delay in data submitting, so maybe it is not yet possible with this feature.
