A few managed apple devices suddenly started showing as inactive in hexnode. The last check-in was about 2-3 weeks ago, but the devices still had wifi and cellular internet access. the apns certificate had expired, so I renewed it from the Hexnode portal and uploaded the new certificate from the apple push certificates portal. The renewal looked successful, but the devices were still listed as inactive right after that. is there an extra step needed after renewing the apns cert, or does it just take time for the devices to sync again?
