Hi all!

I came across a bug with the associations between annotations and documents in firmware version 2020-11-19_13-50_3.0_88a2f03 on the Onyx Boox Max Lumi.
Given the bug characteristics (seemingly systematic) and the shared code base across models, I suspect it may be more widespread.

Annotations seem to be associated with all copies of a given file on the device. So annotations done on one of the copies will be shown on all of them.
One modification done to a file copy on an external source (e.g. the PC) dissociates it from the annotations.
I would therefore surmise the association is based on a hash value (which would imply that (albeit unlikely) mixups might even happen between unrelated documents, should their hash values coincide.

Procedure to verify whether your device is affected:
- copy 3 copies of any PDF or DocX form on the device (2 identical, 1 partly filled in on the PC)
- open one of the clear forms on the Boox and annotate it
- close this copy (by tapping on the 'X' in the tab listing, should you have enabled ' multiple documents' in the NeoReader) and open the other ones

In my case, the second identical file now sports the annotations I have done on the first, while the partially filled one does not show the annotations (only what was done on the PC).
Please note that if you have opened multiple copies simultaneously, it seems to work at first, but you'll get weird effects after, e.g., a reboot.

Can you folks please confirm this behaviour? It makes it factually impossible to fill in multiple versions of a form on the Lumi.
Maybe someone has a suggestion for a workaround, waiting for a potential fix. (Using Notes does not really work, either, for partly landscape multi-page forms)
