Strange behaviour on iOS 11

[longmaba]

Hello,

I have 3 devices: 2 are running iOS 11, and 1 is running iOS 8. I start advertising on all 3 devices, and they can see each other. However, when I put one iOS 11 device to sleep, the other iOS 11 device cannot discover it anymore. The iOS 8 device still can discover the sleep one with no problems.

Do you have any experiences running Discovery on iOS 11?

Did you run into any similar problems? How did you solve it?

Thanks!
