What media types does Genesys Cloud SMS support with MMS?
At the current time, Genesys Cloud SMS supports .jpg, .png, and .gif media in the agent user interface. If an end user sends unsupported media in a message, then the agent receives an indication that a media attachment was removed. If a user sends only unsupported media in a message, then Genesys Cloud notifies the agent that the message has no content.
