When You I want to share a link to a file in the Mail App, the generated API URL is wrong, for example (Please note the "v1shares". no slash between v1 and shares): https://cloud.domain.cl/ocs/v2.php/apps/files_sharing/api/v1shares This URL give you a 404 error. The correct URL must be: https://cloud.domain.cl/ocs/v2.php/apps/files_sharing/api/v1/shares

Click on "Add share link from Cloud Name Files"
