Warmest welcome from the Community team!
Having the choice to create a photo album in which pictures are shown on your device is a great feature to have and we'' make sure we do the steps necessary to return it back to its original state. A few questions: what Nest device do you have there? Has it not been resolved by itself? Could you do a sequential reboot first starting with your WiFi router, then your Nest device. Restarting your phone might also help and tell me how it goes.
