## Bug Fixes

- If there are more than 1000 Leads added as Campaign Members to a Campaign, scheduling an SMS or clicking the **Send SMS** button from the Campaign creates an outgoing SMS in Salesforce and sends it to the Leads/Campaign Members. Previously, the SMS was not created or sent. (Known Issue: 000004699)
- If a Contact related to a Person Account receives an SMS from a Campaign and replies with “STOP,” then the related Account record’s **Do Not SMS (Account)** field will be checked, preventing additional messages from being sent. Previously, SMS messages could still be sent to the Person Account because the **Do Not SMS (Account)** field was not checked. (Known Issue: 000004649)
