@StephanieAshley ...
Even though you may not see employees responding to every posting here in the Community, they do read our feedback here in the Community site. The Community site is just one of several ways that Instructure (the folks that make Canvas) gather feedback from us...the end users. Here is a document that provides some more detail on the subject (check out the section under "Discover"):
What is the feature development process for Instru... - Instructure Community (canvaslms.com)
I watched the video also and it conflicts with what tech support has told me in that after you build the quiz, you have to exit the build and then go back to the details and hit save. So I'm not even sure what to do with that. It is a constant frustration that you can't navigate between the details and the build page also.
I could be wrong, but you may be misunderstanding something about the screens for New Quizzes. If I am interpreting this part of your post correctly, you are indicating that you need to click the "Save" button to save your New Quiz? This is not entirely true. Let me try to explain... When you create a New Quiz in your course, the first screen you would see (before you click on the "Build" button) is the assignment details screen...which is detailed here:
How do I edit the assignment details of a New Quizzes quiz?
Only when you make changes to this particular screen do you need to hit the "Save" button (or the "Save & Publish" button if you've not published your quiz for your students yet).
However, after you've clicked on the "Build" button to design your quiz questions and set other properties for your New Quiz, there is no reason you need to exit out of the "Build" screen to click the "Save" button again. When in the "Build" screen, if you click on the "Settings" tab, all the preferences you change there are auto-saved. There isn't any "Save" button, and again, there's no need to exit out of the "Build" screen to click "Save".
How do I manage settings for a quiz in New Quizzes?
When adding questions to your New Quiz, each question type has a "Done" button at the bottom of it. Once you press "Done" for whatever question you are creating, it is automatically saved as part of your New Quiz. Again, no need to exit out of "Build" and hit "Save". Just as an example, here is the Guide for creating a True/False question in New Quizzes. Near the end of the Guide, there's a section on "Save Question" where it indicates to click on "Done". This is similar for the other question types in New Quizzes.
How do I create a True or False question in New Quizzes?
I took a glance at the Guide called How do I view reports for a quiz in New Quizzes?. You are absolutely right that it says reports could take up to 48 hours to generate. Have you tried reaching out to Canvas Support to report that your reports are taking far longer than 48 hours to generate? If not, I recommend doing that a.s.a.p. Canvas Support would be able to take a deeper dive into this with you. If you contact Support, I would be interested in learning what they had to say...so if you could provide an update in this thread after you speak with them, that would be great! How do I get help with Canvas as an instructor?
I do understand that it can be tough and frustrating to wait for new features to be added to Canvas or things to be fixed. I've been in the same boat with some parts of Canvas at times. While I'm sure that all of us would like Canvas to fix and/or develop "all the things", that's just not reality. Like most organizations, Instructure has a budget to work with, and so there are some things that might have to get tabled for a time that we think should be higher on the priority list. I've submitted some ideas here in the Community that I think would be great in the core Canvas product, and I've waited many years to have them developed...if they've been developed at all. Sometimes I get quite a bit of support from fellow Community members...other times, my ideas don't get much attention at all. So...I get it.
I hope this additional information has been helpful to you and clarifies things more for you (sorry if things weren't clear in my previous replies). Looking forward to continuing the conversation.
