Yesterday an SM that had been online for 7 months suddenly went into "Grant Suspended - IAP Pending". Cambium support theorized an NTP issue of some sort, and they had a pretty specific story about pool0.ntp.org having an issue. By the way, the grant is only for 5 minutes so if your device's clock is off by a few minutes you can get a grant that ended in the past or starts in the future and either way you're broken. So NTP is now a mission critical service. I don't know if an NTP mishap really caused this, but it doesn't sound impossible.
NTP on their side? If it's your side I would say set up some local NTP GPS clock appliances on your network instead of relying on internet time, but if it's a cloud thing then yeah that kinda blows if it's that fragile.
