I have cleared cache, data, uninstalled and installed QB, power off and  on the phone and still the error comes as 'check all details on the transaction or match them on the computer'. I was able to reconcile all the transactions on the same mobile for a year and this has been happening since last week. I am really unhappy that even after calling QB, the person who attended the call was not able to fix the issue.I would like this to be resolved asap or need clear answer whether this is going to be an ongoing issue in the future.
