How to change the timer? I have 2 of my 4 yeelight with timer blocked at 15 minutes and the 2 others at 30 mins. How to change those values?

In the page of Schedule, you can change value of them.

Ok but why some of them have 15 mins by default and others 30 mins? I have not set any timer since I own the lights and more I can change the timer only after starting it, not before.

I think it’s a bug, as in the IOS app i can change the timer value also if it is still not started, while in Last Android Beta App i cannot change this value if i don’t start before the timer… Please check yourself and let me know…
