To accept an invite and join a frame, first your family member or friend will need to invite you to join their frame through the Aura App. You should receive an email from them with a link to accept the invitation and start sharing photos.
Before you click the link in the email, you must create an account and log into the Aura App. Once you've created an Aura account, you can go back to the invite email you received and click on the button in the email. This will redirect you to the Aura App where you can add photos to the frame you were invited to join!
If you received an Aura frame that someone else set up for you as a gift and you are now connecting it to WiFi for the first time out of the box, just follow the steps in the app to "Set up a new frame." Once the frame is online you'll see the photos they previously selected and can invite others to join and add their photos too.
If you require further assistance please don't hesitate to contact Aura's Customer Support by emailing firstname.lastname@example.org or calling 646-630-7237.
