Scaned pictures missing from the notes

Scaned pictures missing from the notes

I disscovered so far 2 notes that dont have all pictures but some pictures have only placeholders and error message.
This is same for web and android versions.
Disscovered it when I needed the note with pictures only to find not all pics are there.
Having in mind that I also have a problem with mising notes in Android, Nimbus is utterly unreliable! For personal notes, maybe, for bussines - I am not trusting it!
