Wow, I can't believe I missed that. Thanks!
That seems like it should work and should fix my original issue. However, now when survey 123 opens up after I click the link, it is stuck in a loop where it shows it is downloading. The image below should really be a gif, just imagine it downloading form then thumbnail and form again and doesn't stop. Any ideas where to look?
Made a new survey to see if there was something wrong with the first one
arcgis-survey123://?itemID=65b123278c8142afbf58bf0b50c4bc36?field:plot={st-cty-plt}
st-cty-plt, itemID and field are correct.
