Ok - yesterday I performed a lengthy update and went to fly. Because of a disconnect issue in the past I want to fly mostly in 5.8 Ghz. After the update, I was not able to locate and connect to the 5.8 Ghz channels. Has anyone else experienced this?

Try to reset, refresh firmware and re-calibrate everything. I use to do that every firmware update to wipe out the most issues. Mine is automatically switched from 5.8 to 2.4 if signal weak. I live in Vietnam btw. Good luck

Hi, I'm sorry to hear about the issue that you are experiencing. Please make sure that you have updated all the firmware to the latest one, I still recommended to refresh the firmware again, at the same time, may I know which mobile device do you use and the DJI GO4 app version, please? Hope everything will be fine soon.
