We have an opportunity out on our site with qualifications that are set to auto-approve. When someone clicks "respond" they are prompted to complete the qualifications. Once they click "submit qualifications" they are not prompted to continue responding. This is a hindrance to recruitment - especially when the qualification is something simple like a waiver that we want them to fill out. People may complete the waiver and think that they are signed up and there is no way for us to know that they were even interested unless we turn off auto-approval - which only further complicates the sign up.
Volunteer should be prompted to select a shift and complete sign up after they submit their qualifications - whether or not the qualifications are auto-approval (but especially if they are). They should be listed as "Interested" or "Shift requested" or "Pending" on the opportunity until their qualifications are approved at which point, they are just automatically added to the opportunity. Making the volunteers respond twice to one opportunity is bad for recruitment and completely outweighs the intended benefits of the qualifications tool.
I believe if an opportunity has all auto-approved qualifications, after the user submits them they should be re-routed back to the opportunity response page to finish up registration. Are you saying that they are not re-routed to this page, or does this page confuse folks and they do not know to scroll down to select shifts or confirm their response?
Once I know more here, I can make more detailed insights in my request notes. Happy to test on your site as well, if you prefer, to make sure I understand the workflow users are experiencing.
