Your linked account may become unlinked from Currence for a few reasons:
You unlinked the account from within Currence app or via the financial institution's external platform.
To resolve: Check the permissions within your external bank's platform. Some functionality may interrupt connection with Plaid.
For example, if your external bank's platform allows you to "hide" accounts for display purposes, it may "hide" the accounts from Plaid.
You removed access to the external account using Plaid.
Account verification failed or expired, which auto-cancels account linking.
