After upgrading the M300 RTK and the RC firmware, I got the following error messages: payload UTC time error, payload CPU usage too high, commmunication error between aircraft and payload. Could be just a coincidence that I got all the errors after the upgrade, still. Any suggestions what to do? Surprisingly enough, DJI support is not very helpful. Told me to "refresh" the L1 through the DJI assistant, which is not possible since the L1 doesn't even have a port. Any help would be greatly appreciated.
