About to close my sole-trader business on 31 March so checked my QF feed. On 1/11/17, I paid £18 for a Zodlee bank feed which worked until 29/12/18. A few transactions since then are not appearing on my Bank Feed (Barclays).
Is Zodlee still working (can only see Yodlee referenced here)
However, when refreshing the data, Yodlee can only go back as far as the bank will allow them. For any missing data, I would recommend trying to get a CSV export of your data and importing it into your account.
If it hasn’t worked for that period of time, it does suggest it may have been a specific issue with your bank (e.g. login details changed, or your setup) rather than a more widespread issue.
What’s the process at the moment when you refresh your feed? Are you prompted for a pinsentry passcode for example?
