All annotations gone after HOURS of work

Hi,

I did hours and hours of work yesterday on a document and around 70 out of my 130 page document (all of which the annotations were done yesterday, the previous annotations had been done a few days before) have disappeared. I worked on the document for a long period of time and I know Acrobat Reader autosaves, but when I clicked ‘done’ on the document and closed my iPad (just the ipad, not the app), they were all gone today when I reopened it. There was no warning telling me the document could not be saved.

I checked both recent docs and documents for the annotations - neither of which had the saved docs. My documents aren’t saved to a cloud just on my IPad device. I’ve closed the app and reopened it and the doc isn’t there either. I’ve yet to turn off my iPad. I am using version 18.12.00 (20181212.095727) of the Acrobat reader and this has never happened to me before on this app, and I use it a lot.

It’s going to cost me time, money and energy to have to re-do all of this work if I can’t recover the annotations somewhere - is there anyway they can be restored?

Thanks.
