Okay I turn everything on, the Drone, the controller, start the DJI go 4 app(samsung tab E)and it shows connected. Everything works fine, video,sensors, gps... everything. But there's no acft ssid in the tablets Wi-Fi settings page. This started after the latest go 4 update. I'm not too worried about it as everything works wonderfully, flies great. Great pics and video. Just wonder if anybody else has had this happen

So you were seeing an SSID before?
It could be that with the latest update DJI has chose to not transmit the SSID.  From a security standpoint it makes hacking the WiFi a bit harder if you don't know or can't see the SSID.  Either way, it's my understanding that the connection is between the RC and the UAV not your phone/tablet.  The connection to the mobile device is made through the USB connection from the controller, I could have that wrong but I believe that is the case.
Bottom-line I don't think this is a problem, unless you were doing something with the system beyond the standard.

What aircraft do you have?

Geebax, probably the P4P since he's in GO 4

Yeah, that's why I asked the question, becuase the P4P does not use WiFi, so therefore there will be no SSID.

The P4P does not use WiFi, are you referring to your P3S and DJI GO? If yes, please try to reset the WiFi.

In use with Go app 3.1.xx and not with the Go app 4.1.xx ? or can i use the Go app 4.1.xx with the P3S too? i think i can not.

Can't, the P3S isn't compatible with DJI GO 4.

...then i was correct,thanks Diana. Can anybody of the software engineers can implement active track to the P3 series ? FW and Go app?
