Pencil Annotations on PDF Files Disappeared - Recurring Issue
Just lost 12 pages worth of annotations on my PDF lecture notes. This has happened to me multiple times before regardless of file size, but this time I lost about 5 hours of work which is completely unacceptable. The whole point for me getting an iPad instead of a laptop was to be able to use the pencil annotation feature to directly write/draw on documents.
As I understand, this has been an ongoing issue that Apple has yet to remedy or even address as all the prior instances of similar complaints have been archived or disappeared. I'm assuming this will never be properly fixed, so I'll be migrating to a different OS and platform, but I would appreciate any suggestions in the meantime that could prevent this from happening again.
Things I've tried with varying degrees of success:
Massively reducing the PDF size by breaking it up into smaller files
Keeping iPad plugged in for the duration of the annotating session
Running on low power mode
Converting to .docx format and annotating through Office 360 (Has it's own host of issues)
Annotating files saved locally and through iCloud
These are just the ones I remember off the top of my head, but I've still lost annotations using these methods before. Suggestions for other tablet devices would also be appreciated.
