I have 1 user who uses the mobile app to record his receipts & then uses a desktop to work on & submit his reports. He has had trouble in the last couple of months getting his credit card transactions to download consistantly. There are periods of time when his transactions just do not download. We have unlinked his credit card from his account & then relinked it. When it is relinked, it seems to download correctly, then it will randomly stop downloading consistantly again. Is there a reason this happens? What is the correction we need to make?
