Hello,
Very new to Insights, still playing around. I added some Datasets via the New Dataset button but they don't actually appear there once uploaded. I can tell that they've been added; the below picture shows that I actually tried to add them multiple times since they didn't show up. you can also see that I have an Insights Workbook as an item in AGOL:

However, my Datasets and Workbooks tab remain empty:


Interestingly, the home tab shows my workbooks, but no data:

Is there something going on here that I'm not understanding? I created the dataset and it's shared with the whole org. so I am not quite sure why it wouldn't show up.
