Hi friends,
Need some ideas from you.
Not sure if I miss something but I just got lost today when I tried to configure frontend instance class from F4 to F2 for one of my applications (let's called project-A).
The way to set frontend instance class in app engine admin console changes as below:
The other applications looks normal as before, there are some configuration inputs like Frontend Instance Class, Idle Instances, Pending Latency:

Now I'm not sure what should I do to set frontend instance class for project-A?
The most confused point is, why the other applications keep without any changes but only project-A?
If you know the reason, it would be much appreciated to share me know.
