Ps4 friends are shown offline even though they are online?

I have the following problem, my friends are shown to me as offline on Playstation 4 even though they are online at the same time. We want to play GTA 5 online together, but since they appear offline, neither I nor they can join each other. That makes playing impossible as a TEAM… Do you have any solutions?

They switched to offline in the quick menu.

Then you have switched to offline.

This can be set on the PS4 whether the online or offline should be displayed.

Have a look under Settings.

They probably don't want you…
