• Я хочу найти, какое устройство не смогло получить уведомление IOS.
• Некоторые устройства получают уведомления, а некоторые не могут получить.
• Я хочу получить неисправный токен устройства, на который не пришло уведомление.
• И неисправный маркер устройства вставляется в мою базу данных. Как я могу ?

• Можете ли вы помочь мне и дать правильное решение для получения неисправных устройств токенов. ?

• Заранее спасибо !
