Hello the software shows firmware mis-match but it doesn't update, i tried to refresh and nothing happens, and i cant get my osd to work with the A2 controler... i have tried with an IOSD mini and it does the same thing... is there a problem with the DJI server??

What version assistant are you running?

I recently had a similar issue when I was testing a different A2 controller than I normally use. When I put my old A2 back in I had an error that said I needed to update but you can't update through the software unless you are longed into your DJI account. (both A2's had version 2.3 on them). It just says that you are up to update. At start up of the iosd assistant, it says there is a software mismatch. The software does not tell you that you are not successfully logged in. Turns out I was using the wrong password. Make sure you have the correct user name and password or you won't be able to update. Until the update was done the IOSD would not show any data from the flight controller. Once I was able to get the update in everything started working again. It's all in the update! When it says you are up to date, don't believe it if you not getting data from the controller on your FPV monitor.

Problem was that the dji server was probably not working... today the firmware updated without a problem
everything is working fine now with the update, now i just hope this updated iosd  still works in my old wookong controler
