Why Do I Need to Refresh the Apps on Altstore Every 7 Days?
为什么我需要每7天刷新一次Altstore上的应用程序？
Because the certificates expire every 7 days if you use a free Apple ID. Those with paid developer ID do not face this and it cost $100 per year. This is why AltStore tries to refresh your apps regularly; ensuring you can do this at least once per week stops the certificates from expiring.
因为如果你使用免费的苹果ID，证书每7天就会过期。那些使用付费开发者ID的人不会面临这种情况，每年要花费100美元。这就是为什么AltStore试图定期刷新你的应用程序；确保你可以每周刷新一次，以阻止证书过期。
