I've been linking Collector for ArcGIS with Survey123 through the descibed custom url-scheme. One thing I'm noticing is that the passing of decimal values through a pop-up doesn't work well.
Steps:
1. I have a feature service with a few "double" fields, of which I want to pass the values through to my Survey123 form. I've configured the AGOL-pop up to do so accordingly.
2. When I click the custom URL link it opens up the correct form and passes on all data correctly apart from the decimal data. It does fill it in in Survey123, but flags it as incorrect (red) because it uses commas instead of points.
Expected behaviour:
I'd expect Survey123 to know how to register a decimal value from AGOL/Collector, so that I can pass it through from an existing feature service.
