Ps4 Minecraft Bedrockedition - After update i.a. Minigames and texture packages gone?

We bought Minecraft in the Bedrock edition for the Playstation 4 some time ago. Everything worked out fine, there were also mini games and texture packages. After the bee update, the minigames and texture packs were suddenly gone. Research showed that you can switch back to the "old" edition with the mini-games using the button on the Minecraft homepage, but we don't have the button. Why? Can you change that?
After all, the mini-games were there when you bought the game and the best thing to do now is to buy the games in the store again and also purchase a paid membership to be able to use the games.

Any tips? Thank you in advance.

P.S. Where do you get minecoins from? Sorry, stupid question, are there any prepaid cards (codes) to be redeemed in the Minecraft Marketplace?

That is normal. There are no more mini-games in the Bedrock edition. It is the same as for the flatland worlds you created yourself. But there are dozens of servers that you can join, there will certainly be mini-games somewhere. You should have a look at the texture packs in the in-game store, because you can / have to download the packs IN THE GAME.
