Hi Zeau,
Thanks for reaching out to the community! I understand that you're looking to receive the promo code again to upgrade your current Nest Learning Thermostat (1st or 2nd gen) for the Nest Learning Thermostat (4th gen). I can definitely help you with that.
In case you were unable to locate the promo code, could you please check your spam or junk folders? The emails are occasionally filtered there.
If you've already checked and can't find it, or if you were unable to use it for some reason, the team would like to learn more about this situation. When you get a chance, please fill out this form and let us know when you’re finished. We’ll have someone reach out to you via email from there.
Keep me posted.
Best regards,
Jenniffer
