In Desktop version i can do backups. then if i make a mistake or huge errors, i can simply restore the previous version. how can i do this with Online, as i made an error by deleting a few transactions in teh bank statement. i dont want to have to go month by month for the last ten years of my data to look at it. i just want to restore to the previous point and continue?
