hi
thought the server problems was solved at dji as i cant see any update banner but i can see the version of app 3.1.1 for android and firmware 1.7.9

When I connect the Aircraft body to the PC via USB to view flight logs the Banner appears after I disconnect and restart the aircraft. Try that. Just follow the instructions for entering flight log mode.

Hmmmmmmmmmmmmmmmmmmmmmmm

well then i have to stay on 1.7.9 and its giving me great distance up to 1 kilometer even in a olace where there is many buildings

May I know you've got it sorted out or not?
If still the same case, please try to connect it with an iOS device, which may help.

In field where is READY TO GO sign when i start flying   , start blinking red, firmware update require for few seconds but i dont see the app give me update. I am on android.

still no update banner and i dont have an ios device so im stuck on 1.7.9 but its ok itd working well here

Finally the update banner showed up after plugging the drone to my usb on the computer and then start the app
