I can’t seem backup my configuration — when I go to “Lightning Settings” -> “All Settings” -> “Backup, restore or export template” and select Backup and OK to accept the default name, I get a “Backup error, please check that there is enough storage space on the sdcard”.  If I try to specify a full path, such as /storage/sdcard1/download/BackupName to a place I know is writable (as tested using File Manager), I get the same error.

Anyone know what might cause this?  What is the path where Lightning Launcher saves the backup files by default?

Thanks in advance!  LL v12.0.1 (r2021)
