Steam account version does not sync to GeForce NOW account.

Since the expansion released, Path Of Exile lost sync from my GeForce NOW account.
Sure, I can play the game through my Grinding Gear Games account, because it can be synced there, no problem about that.
All of the GFN supported games are synced to my GeForce NOW account, including Path Of Exile 2, but since the Keepers Leaguse started and the expansion got added, my GeForce NOW account can not sync the game from Steam.

I've already reached out to NVIDIA about the problem, but sadly, they don't have a solution for the problem at this time.

If the problem is on GGG's side, can you fix it, please?

if anyone is interested, this is how I solved the case.
nvidia custhelp has this note:

Free-to-Play or Demo games that have never been played before will not sync. Prior to launching these games, you will need to manually add these games to your library by pressing the button MARK AS OWNED > NOT NOW > YES, CONTINUE in order to play them on GeForce NOW.
in my case i never played the steam ver, just GGG on GFN, so instead of clicking Sync on step2, I followed the advice and clicked NOT NOW->YES and it worked.
