WiFi keep on during sleep setting missing after latest update

[TNJGB]

Previously within WiFi settings there was a setting called "Keep WiFi on during sleep" and there were the options of Always, While charging and Never. I can no longer find that option and it causes me an issue in that various apps of mine are set to back up over WiFi only and they used to do that overnight and now as the WiFi is not on during sleep these apps do not back up until I wake up the phone and WiFi resumes.

Does anyone know if this setting has moved or it it has just been removed?

@TNJGB: I have looked into this for you, and the 'Keep Wi-Fi On During Sleep' option is no longer available. I'm not sure if this will work for you, however you may wish to try heading to Settings > Apps > Select an app you would like to backup while the phone is idle > Battery > Allow Background Activity > On. Let me know if this helps.
