Issue: I'm running my phone/iPad/other iOS device on Low Power Mode and Freedom stopped working.
When iOS "Low Power Mode" is on, Background App Refresh is turned off and Freedom cannot receive session updates. Low Power Mode sometimes goes on automatically. When it's on, you'll see a yellow battery indicator in the upper right. It is advised to allow it to come on when needed in order to preserve your battery. But it may sometimes be useful to turn it off in order to debug Freedom functionality. To turn it off:
Navigate to Settings → Battery
Ensure that Low Power Mode is off
