Shortly after installing v15, Apple PUSH notifications started to fail for a customers all-mobile support center. Wasted a lot of time and effort that morning trying to diagnose, and then quickly applying updates. Same thing yesterday, Certificate expired again. Im not into software dev, so I dont know what much about APN, but I know I can get an SSL cert good for years. Is there a 1 year limit from Apple on this ? Should I expect this to happen every year ?
