So I made a notification ringtone with ringdroid, selected it within calendar settings and tested operational last night. Today, I get no notification. Upon going back into the calendar settings, I discover my made ringtone is gone. Its still in the ringtone notification folder and I've also moved it to the regular notification but still don't have an option to select it for use.
Between working and not, I've since rebooted phone. I'm running sapphire.
