I have a Survey123 connect application that is now issuing an error on startup. Basically it is getting Error.Initializing Form... Type error: o.split is not a function. I believe this error is new.
Any idea were I should look within the xlsx to determine what is causing this?
It sounds as if there is an expression in one of the calculation/constraint/relevant columns that is not valid. Can you please share the xlsx file so we can take a closer look?
I tried the xlsx form file you uploaded to your original post, and can not reproduce your error with latest 3.9 version of Connect. I do not get an initializing error and the form loads correctly in Connect and I can publish and collect surveys. Have you tried re-installing Connect or opening on another computer?
