CloudKit PublicDB stopped working today (worked yesterday)

My application is using a Public DB to share information to all apps. It was working fine until today. Also I don't see Logs on CloudKit Dashboard (or History or Live). Call self.publicDB.perform(query, inZoneWith: CKRecordZone.default().zoneID) never finish. I tried Operation as well -same result. Anybody experience same issue?
Nevermind. For some reason app got removed from being "iCloud app" on a phone (was no longer shown under iCloud apps on settings). Don't know why this actually happened - reinstalling app multiple times didn't help. What helped was - restarting the phone...
