Fix List Web Part Expand/Collapse View on Modern Site Page
When attempting to display a list view with grouping turned on to have expand/collapse functionality on a SharePoint Online Modern Site Page multiple lines of text values do not show. If the multiple lines of text field is required it shows "Required Info" even when values exist for that field. When the multiple lines of text field is not required the field shows as blank even though a value exists. The only way to see the value is to click the heading which takes you into a separate page and shows the field values.
Is there a resolution/workaround for this? I am having same issue.

I'm also having the same issue when I group list items and show it on expanded view.
I'm having this same issue today. If my item has a date field filled out, it will not show up. I expand the grouping and nothing loads.
