How to check if player logged in Google Play

I really hope this is the right section as I’ve made a game that’s 99% complete EXCEPT for one thing that I have spent a lot of time testing but lastly quit for almost half a year now as I can’t find a solution. It was made in 4.8 so I hoped 4.12 had made it easier but no I guess.

Here’s my question:
According to Google Play, my game NEEDS to have Achievements. To do that, I need to make sure a player is logged in to Google Play every time they launched my game. Question: HOW DO I DO THAT? I’m using Blueprints by the way.

I need to know which nodes to use, from the moment my game loads, and where to use them. I don’t know the proper flow to implement this system. Hopefully by now some whiz developer has found a simple way that I can understand. I had spent months creating my game only to stop for few more months as there’s no answer…this has been bugging me so I really hope I can get it out even if my game will never get any downloads.

Hi, I believe there is a “Is logged in node”.

Use it on on the player controller.
