I try to setup the backup of my Samsung Galaxy S8 (SM-G950F) using seedvault to a new SD Card of 64Gb (formatted, empty with read/write capabilities). When I run “Save now”, I have the error message “Backup not enabled”. I have checked the access rights of the app and they are set to all files.
Same message when I try to backup using nextcloud.

@piero and @tcecyk : thanks for your answer and your links. Your answers save me time, I will not try any more this useless app. I will continue to use adb from my computer for full backup.
