When device sends uplink with ACK bit set to 1 Chirpstack indicates it as error frame with error message "invalid MIC". This happens with LoRaWAN 1.1 OTAA and ABP. LoRaWAN 1.0.x OTAA and ABP works just fine.
If I manually set bit to 0 on device end before transmitting there is no error. Also when testing device with Actility ThingPark messages are received just fine with ACK bit set to 1.
