I had a multiline text field. In the PowerApp list form I removed the regular field and added a Rich Text Editor Field and bound it to the field. When I save the form the data in the field does't always show in the SharePoint list. However, as soon as I filter that field it will start showing. If I export the list it shows in Excel and when I open the form it also shows.
See attached images. This has to be a bug! Has anyone else experienced this?
