It may be a bit tricky to say at this stage - if the date was within the last few days, we probably could have said with more confidence, but I will take a look to see if there is anything logged with Yodlee.
If you’re concerned that data may be missed, you may find it best to do recon your bank details against a statement: Reconciling your bank
[Edit]
@concentric - Just to confirm, there aren’t any errors found for your account, but these may very well have been removed given the time since the gap happened. If you do notice these again, please don’t hesitate to contact us and we’ll take another look for you.
