2) Your bank account information changed - just relink your bank account through the prompts in the app and you should be all set.

4) We weren’t able to request the the daily payment from your connected bank account. Try reconnecting your bank account to troubleshoot - it’s easy to do so in the app. If the issue persists, contact support.
