@wroos this has actually been a mystery to me until solving this issue today: Export Failed Error message while downloading data from KoBoToolbox server - #24 by babajide_oluseyi
If I replicate the issue on that thread, trying to edit submissions reproduces the issue on this thread about the “Start tag…”. Hopefully resolving formpack#303 will fix both cases.
There was additionally an issue here that caused this: Changes in pyxform behavior break submission editing · Issue #3751 · kobotoolbox/kpi · GitHub
