In Let's Load your software .... I already have surveys and survey123 connect xls files. If I do what you suggest of coping them to my desktop will that break the existing surveys? My work around is Pinning the folder to Quick Access - but you might want to mention this.
From Understand How Survey123 Connect ... you mention hosted surveys but not ones based on reference layers. Will you be discussing those in this class? I worked at an org that would not let us use hosted layers - so this might be relevant to some folks interested in your community.
My GIS superpower is probably breaking Jack's software. If they staffed me to QA/QC their development so many unfound bugs would be resolved before release.
