Our Portal enterprise is currently being re-indexed and it is taking days rather than hours. My personal account does not display any content, but I can still publish to it, send data via an already downloaded form and view the data via ArcGIS Pro, etc. When I try to download a form onto a mobile device there list is empty. It brings up the question of whether or not you can sideload a form when your Portal account is down. Can you? Thanks.
