If your flattened Xero data does not look correct, please let Flatly Support know right away by contacting us via the in-app messenger in the lower-right corner.
If your job failed, checking your Logs (upper right menu on Scheduler Page) is a good idea to find out what may have caused a job to fail.
You should definitely let Flatly know if your job fails repeatedly and the job failure message does not help you resolve it easily (your cloud storage folder may have changed, your authorization credentials changed, etc.)
