I have no idea how the premium version differs much from the free version at the moment since the current version is almost exactly the same as the free version. 

What differs from the free version? Only two things: showing the last CG of the chapter with the sprites of the Priestess and Zero blocking the CG and every ending is Six asking to buy the Premium version.

So, either the problem wasn't fixed or the wrong version of the game was mistakenly updated and then uploaded instead.

I would like to read the extra content, so I hope the problem gets fixed.

Hi, I downloaded the game today on my Computer (Windows) and it seems like there's no Premium Content available. 

I guess so because I remember some special scenes like the one where Zero is hacking the elevator while infiltrating Kairos (is stuck in my head because the artwork was so beautiful, so shout out to that artist) 

Anyways there weren't any special scenes and I was really looking forward to playing this stunning game again

Hope you'll find the problem and I hope you had a good start in the new year! 

Can confirm. It does look like Premium content is locked for now. I have that version as well and started up a new game to see what choices were available. No premium choices/CGs were available; whereas they were prior to the update.

Hey, I still can't get access to the Premium content either, even though I have that version. I can't choose who joins me up at the rooftop to go and see Nish, and therefore who we write our letter, or any of the other Premium content or CGs except the last one. And I still get Six as the default for the Nish visit and  with the prompt to buy the premium version at the end. (So same issue as Shinrai.) Also, I'm using the app on Mac.

Good morning, I am sorry to say that it still doesn*t work for me either. The Premium Choices still won*t show (I started a new game to look and loaded an old save file, as well, to compare). When my MC thinks of the one closest of her it is still just "him" (without any name) and all the CGs are missing except for the last one, which is still behind all the other character sprites in the scene. I also ended up with the neutral Six Ending where he told me to buy the Premium Version. I wish you a happy new year. Don*t know what causes the issue.

It seems I still can't access the Premium content, neither with a previous save nor when starting a new game.. Fingers crossed the issue is only on my end and no one else has that problem anymore, this bug seems to be giving you trouble for a while now. I hope you have a Happy New Year!
