That should not be the case, but it guess comes down to their own system design. I will escalate this to our Open Banking contact at Barclays, but they are taking 3-4 days to reply at the moment. Many banks are responding much slower at the moment with all the PSD2 overhead.
Unfortunately regarding Yodlee, we don’t have any control here, as to my knowledge the FCA have required Yodlee to close down those feeds on 14th. Sorry I could not be of more help here.
