Hello I am having a very similar problem to the one reported in this post.
Hanging when trying to publish update to Survey123 form
I created a log file and have attached it to this post. James Tedrick
Any suggestions on what maybe going on I am all ears. I am trying to publish to a 10.5.1 portal. I made a simple form and was able to publish so I am wondering if the form is too complex for the old portal. How would I simplify the form. The form has groups and and use pages styling. I also use a repeat to capture pictures within each group of questions.
