Upgrade StorageAbout cloud synchronization between multiple devices (webdav)
Hello, I currently use Windows and Android devices. I encountered this problem during my use: when I changed a note on my computer, I then opened the Zotero software on my phone and opened the note, and found that the note was in the state before the change; then we returned to Zotero on the Windows system and clicked the sync button, and were surprised to find that the note here also returned to the state before the change, which means that the change I made was invalid. My devices all use the webdav function.
Then I conducted several experiments and found the reason for this phenomenon. Suppose the state of the cloud before taking the note is a, and after I modified and synchronized it on the computer, the cloud changed to b (all devices have been synchronized at this time). At this time, I opened Zotero on my phone and quickly opened the changed note (before the automatic synchronization completion prompt), and then the old note was uploaded to the cloud and overwrote the modified b state, resulting in the loss of the note.
