Transactions posted to your bank account don’t import to Wave instantly. While it normally tales 1-2 days, depending on your bank, there may be a longer interval between transaction imports. It can sometimes take up to 7 days for transactions to import.
Transactions import automatically and it’s not possible to initiate a manual refresh. If your transactions have not imported in over 7 days there may be a technical issue that needs to be resolved by Plaid. Learn more in Why is my bank unable to import transactions?
