There were a couple of long standing bugs with annotations that were fixed in 2.3.1. And until last the week, I would have said everything was working OK. But, I have been reading a couple of books and recording corrections as annotations and have lost a few. I haven't worked out a pattern, but the two or three times it has happened, I have lost all the annotations on the book.
In each case, I had made some annotations while reading, used the annotations to correct the source and deleted each annotation. At the end I had no annotations left. Then when reading the book again, I made more annotations. The next night when I was at the computer, I discovered there were no annotations. But, when reading the book again the annotations were saved and there when I went to do the fixes. I don't know what was different about my use of the device when I lost vs didn't lose the annotations.
