Late downlink scheduling

Hello togheter,

I am using dragino LT-22222-LT togheter with an Dragino LPS8v2 Indoor Gateway.
When I am sending over API an downlink to my device it takes a lot of time to send the downlink to the device.

I just checked to documentation for CLASS C and added to my downlink call the class_b_c function. But also this is not working in minutes. The downlink is still without respond in the dashboard. Sometimes I also get the error TOO_EARLY. The devices are all standard configurated with Class C activated in the dashboard. Or does I need to use the CLI to update the device?
