Hello there, @Laura_C.
Let me share some information about downloading bank transactions from Chase Bank.
Currently, we have an ongoing issue when updating the Chase Bank. It shows duplicate transactions in the account.
Our product development team are working with your bank to resolve this issue, and we're going to roll it out as soon as possible. For us to send you an update, I recommend calling our phone support so we can add you to our notification list.
You can find our contact information here: Get help with QuickBooks Online.
We appreciate your patience while we look into this. Please stay in touch with us if you have any other questions.
