Thanks for posting and we're sorry to hear about your concern with your TP synchronization with your iPad. It would help a lot if we could isolate this further since this channel is for troubleshooting Google Nest devices. What Nest speakers do you have? Are they all working as intended? How about your TP device, what type is it? Does it disconnect from Wi-Fi or from your iPad itself? Is it working via its native app?
I'll be waiting for your response.
