I previously installed two Nest Cameras (one indoor and one outdoor) using the Nest app with a Google account. I have since added two new Nest Battery cams. All four cameras connect and work fine in the Google Home app on my iPhone, but only the two new cameras will connect on my iPad. The two older cams will not connect, though they appear in the app.
Is there possibly a difference with the iPad app? It knows the cameras exist, it knows they are connected through Nest, but will never show the video or history. The phone app does both live video and the full history without issue.
Sorry for my late response. Thank you for all of your patience while waiting for a reply. I can definitely understand how frustrating your situation must be. I just wanted to make sure that your issue is addressed.
Please let me know if you need further assistance.
