Sometimes the permissions with your iPhone get reset. 1 Second Everyday needs these to work correctly. To make sure the app has the correct permissions tap on your Profile picture at the top left of the home screen > Settings (gear icon at the right) > "More Settings..." > "Manage Permissions".
This will take you to your phone's settings for 1SE.
Verify that Microphone, Camera, and Media & Apple Music are enabled and that the app has access to All Photos.
TIP: Everything toggled on, but it still doesn't work? Try turning these off and then back on. Sometimes a reset helps.
