I'm facing an issue with ArcGIS Survey123 involving an external choice list and seeking insights into its root cause. Our setup has multiple surveys in ArcGIS Survey123 that utilize an external choice list. This choice list is in the form of a CSV file that we've uploaded to ArcGIS Online. The CSV file comprises three columns: 'id', 'name', and 'label'. This list contains approximately 10,000 choices.
Initially, everything worked smoothly, and participants could select choices from the external list while responding to the survey. However, a peculiar problem has emerged. The link between the external choice list and some specific surveys seems to have broken. Users can view the choice list correctly when providing responses, but upon saving a response as a draft or submitting it, the chosen value transforms into 'name' instead of retaining the actual value. Notably, this anomaly is occurring only for certain surveys. Other surveys using the same external choice list remain unaffected.
This issue had occurred before, and I was able to resolve it by re-establishing the link between the external choice list and the survey through Survey123 Connect. If anyone has encountered a similar issue or possesses insights into what might be causing this behaviour, your input would be highly appreciated.
