How can I stop the push notifications from waking me up in the middle of the night?

If you are on an iPhone or iPad, go to "Settings" and then "Do Not Disturb" and set your phone to not make a sound during certain times of the day (e.g. 10pm to 7am).  If you are on an Android phone, there is a "Do Not Disturb" mode that you can turn on before you go to bed. This will stop sounds and vibrations.

Did this solve your problem?
