Backup your Citrine database just to be safe, but you should be fine.

Should I "Download all Events" first, and then "Export Database"?
When I downloaded all events, Citrine asked for amber authentication...
Now I see Citrine as an app in Amber for the first time??? Was Citrine not working the whole time? I could always see the list of different kinds, but never listed in Amber... Maybe since it was local it didn't need signing permissions??? I dunno... So much to learn...
The permission for Citrine to use Amber was only a few versions ago. It probably was working fine.
