I am new to GIS and ArcGIS online platforms. I added an Excel(.csv) file first with relevant attributes. Then I hosted it and added 27 points by giving details of them in ArcGIS map viewer classic. When disabling editing points the popups show correctly in ArcGIS map viewer classic. But when viewing feature layer in ArcGIS map viewer points are not showing. My objective is to create a dashboard for this data. When I share data to a web app and create a dashboard any point is not visible there also. I would be very grateful if any experts could help me out to solve this.
