After the 1.21.60 update, when I visited Frozen Ocean and Frozen River biomes, these biomes didn't look right. It seems that a Snowy Plains or a Snowy Beach biome is generated within frozen biomes in random chunks, and that this happens in the worlds created before the 1.21.60 update.
My friends also saw this bug (one of them plays Minecraft with iPad) so I think this might occur in any platform.
How to reproduce:
1.Enter your world. The world must be created before the 1.21.60 update.
2.Visit Frozen Ocean or Frozen River biome. The biome must be generated before the 1.21.60 update.
