Same issue, I potentially lost a very valuable amount of work for a customer of mine.
Images not loading in a specific note, on Desktop and Web alike. Images were orignally pasted in PNG in another note, then cut-pasted in the current note.
Desktop version :10.70.2-mac-ddl-public (20240102101123)
Browser :Firefox 121.0
Very worrying that this problem has apparently been running for a long time without being fixed. Can I still trust this software with my data of should I switch to something more reliable where my work is not randomly erased?
