Good day everyone, I purchased the Kasa Smart Wi-Fi Light Switch Single Pole 3-Pack and installed two of the switches in my home. I downloaded the app and connected them successfully and they worked without issue. I set a schedule on the app for my living room switch to turn on at 6PM and turn off at 6AM. The scheduled worked everyday without issue until today. At 6PM the switch turned on, I went to bed and woke up after 6AM to see that the switch was still on. I installed these switches exactly 4 weeks ago and have not had any problems until today. Can anyone help me identify what could have caused this?

Update: I just tested the scheduling and it works as it should. Still unsure what could have caused that issue.
