When built on a planet, the warp gate gives you menu and page to find info, activate warp gate, and see cool down https://prnt.sc/pziw5f . However when built on the PPS there is no menu or page to activate https://prnt.sc/pzix86 , you have to go thru the building info to activate on PPS https://prnt.sc/pzivlq . I do not know if the warp gate is supposed to be able to be used on PPS or if there is just no menu and page for it on them.

Hello AdmiralAckbar, it looks like this is not actual anymore. I didn`t find any PPS with warp gate
