Hi @mikhail5522,
Sorry to hear you’re encountering this issue. Just to be clear, you’re seeing the same issue across all three devices? When you say “at the very best are coming in 10-15 minutes later”, that implies some events show up later even? And to clarify, is the data showing up in Notehub but not being routed to your cloud app until later?
The good thing is the Notecard is not a “fire and forget” device, so any data not successfully sent to Notehub is still saved in flash and retried later. What you’re describing could also be a cellular connectivity issue as well (this can be difficult to diagnose without getting a trace log if that’s possible?).
