True. I preordered the digital version of GT7, downloaded it and thought I'll play it after work, but then found the game locked and money returned to my PS Store wallet. The game was just removed from the Russian Store. But other games were available to buy, and the game servers (including GT Sport) still work. Some other Russian and Belarusian players said they were able to start the game after midnight of the launch day and play for few hours, but then were kicked out mid-game and weren't able to start GT7 again.
Possibly, this could have happened because of ruble devaluation - the base PS4 version costed 4999 rub, which used to be roughly $65 before the sanctions hit, but now (as I am typing it) it's only $40.3. Which is why the game may return to the Russian PS Store later, but at higher ruble price.
The Russian division of Sony said - "GT7 launch is delayed in Russia. Details about release are expected later". The physical copies also haven't arrived in the retail stores.
However, there is still a way to buy the game using a foreign Store account. At least one simracing YouTube streamer got a copy from UK Store and it's playable on the Russian account.
