We are using OnlyOffice integrated to NextCloud.
When we use spreadsheets collaborative editing with multiple users Redo / Undo is unavailable some time.
example
if user1 & user2 changing in file same time Redo / Undo is not working.
if any changes done by user1 Redo / Undo is not available for user2 or if any changes done by user2 Redo / Undo is not available for user1.
Is there any solution that both users can do Redo / Undo their changes.
we are open for both free / paid solutions, if available.
