I have spent 2 hours updating all my transaction information so that everything was up to date and no transactions needed to be reviewed. Dashboards, etc all showed correctly. However, when I logged out and went back in again to check something everything had reset itself and it now says there are more than 20+ transactions to review - these are all the ones I had dealt with. Is there anyway of sorting this so that I do not have to re-enter all the information again? I cannot see a way to contact QB (UK) regarding this.
I don't want you to re-check the bank transactions since you've already reviewed them, PurpleJay.
