I found this from U-Tec in my spam folder:
Dear Customer,
Next week, we will be releasing a crucial update for the U home app. This update is essential to enhance the security, stability, and overall performance of our product.
To ensure your app continues to function optimally and to receive future updates, it is imperative that all users install this update. Upon receiving the in-app notification next week, please update your app immediately.Your prompt action is vital for maintaining the best service experience. Thank you for your cooperation and continued support.
It’s a little disconcerting that this email doesn’t mention why this update is so crucial that a separate email blast to all users was deemed necessary. Is there a security incident?
