Daily update is an Assistant feature that allows you to provide a short notification every day for users of your Action. The notification will appear on mobile devices only, not voice-activated speakers or smart displays.
Make sure you show the value of your Action and prompt them for daily updates only when it makes sense. Adding daily update subscription prompts mid-conversation or as a suggestion chip in the end of the conversation can be frustrating for users. Also, make sure that your daily updates will result in different and useful information every time. This is the only way to keep your users engaged with your Action. Test your daily updates using the Actions simulator on an Android or iOS device. You can also use your own device to invoke your Action and subscribe to daily updates, then check the Assistant app for notifications around the scheduled time.
