Sandglass does not ring until my Xiaomi phone is unlocked.
The MIUI on Xiaomi phones restrict third party applications' access. As such, it might be restricting Sandglass on your phone. Please look into the following steps: 

1) Go to Settings > Manage apps' battery usage > Select Sandglass > Select "No Restrictions." for Sandglass
2) Go to Settings > Permissions > Autostart > Select Sandglass > Turn the toggle to switch it on for Sandglass
3) Go to Settings > App Notifications > Select Sandglass > Turn the toggle for "Priority" on.
My custom ringtone (in my ringtone library) does not play.
Unfortunately, this is a problem we have been trying to resolve since the initial development stages. This is a Android-specific problem which we have no means of resolving at the moment. We suggest you use your custom music or phone's default ringtone as your alarm ringtone.
