I made some minor changes in the survey forms attached.
Data for V2 is viewable in survey123 online, but the arcgis online map returns the title error and will not populate any data.
I can still submit additional surveys and I don't believe any of the issues noted here are relevant.
Aside from removing the changes (I think they're just in the calculation field) I can't think of anything that would be generating this error.
Any help is appreciated.
