Why has my Moto app stopped working since Lollipop update?

[AC Question]

My Moto app on the Droid Turbo (which is a built-in app) that allows no meeting interruptions, has a sleep mode and even reads my messages aloud while driving has stopped working since the Lollipop update. I can still access the app and it appears to be working (as it syncs to my calendar) but push notifications still come through while I'm in meetings/sleeping. Even calls come through on the meeting/sleep mode even though it's set up to be "priority only". I've cleared my cache on the app but that didn't seem to do anything.

Please help as previous to the Lollipop update this app worked fantastic. Thanks!
