Make co-authoring (syncing) work
Currently, the co-authoring function works poorly on the Window Word client. The syncing lags significantly and it is so bad that real-time co-authoring is virtually impossible due to the text not showing up in real time, causing the texts to be locked. Moreover, whenever someone types more into the document before the slow syncing completes, conflicting copies of the same documents would be created and the OneDrive client will relentlessly ask me to choose an action to resolve this, and then only lead to losing information on either of the copies.
Please fix real-time co-authoring.
