You can hide an account or disconnect an entire financial institution at any time by going to “Profile” on the top and then “Accounts.”
To hide a specific account, select the relevant financial institution (e.g. you could have multiple account in one financial institution: saving, credit cards, checking), then click on the menu next to the specific account in question and select “Hide Account”. This will keep the financial institution connected, but will remove the specific account’s data from all features within the app.
To disconnect an entire financial institution, click on the menu next to the relevant financial institution, select “Delete Institution” and follow the instructions on the screen. This will disconnect all of the accounts with that financial institution from the app.
