1. When adding a voice recording to an image in your memory, you must find the memory you would like to edit and go into edit mode (Find out how to here).
2. Press the orange circle button with the microphone icon next to the voice record label.
3. You will be asked to 'Allow' the microphone, as seen in the below screenshot. This step should only be required the first time you access the microphone. Once you click this, recording will begin.
4. Once you have finished recording your message, click the orange button again. The icon will change to uploading and, when finished, the Memory Save button will change back to orange and allow you to save your changes to the memory.
