This is the game working as intended. For a villager to restock their trades, they must have a work station and be able to pathfind to it. The block a villager uses as a work station differs based on its profession. You can read more about these mechanics on the Official Minecraft wiki.
Have you downloaded the free Music Pack in the marketplace? Without it, you won't be able to listen to music disks.
The reason that you cannot mark Future Releases as affected by this bug, is because you do not have access to them. Since you have not played them, you have no way of knowing or verifying whether the bug is still present in the Unreleased Version.
This is the game working as intended. While observers will detect a note block being played on Java edition, on bedrock, this is meant to not be the case.
Did you get this fishing rod through fishing or finding it in a chest? If so, there is a chance that the fishing rod generated with the enchantment "Curse of Vanishing". An item with curse of vanishing will not drop from a player's inventory when they die, but instead the item will be destroyed.
What difficulty is your game set to?
On easy mode, villagers can never be turned into zombie villagers, and on normal mode, there is only a 50% chance that the villager will become a zombie villager.
This is most likely the game working as intended, however, you have not provided enough information to verify this.
Villagers must have and be able to access a work station at certain times of the day to refill their trades. While normally these would spawn naturally in villages for villagers to use, it is possible that you removed the villager's work station.
This is the game working as intended. Piglins will attack you when you open or brake any containers near them, including chests, ender chests, and barrels.
Here is a quote from the Official Minecraft Wiki:
"Piglins are provoked when players (with or without gold armor) attack them or when a nearby chest, trapped chest, ender chest, barrel or shulker box is opened or broken."
This is the game working as intended. As of version 1.16.1 of bedrock edition, mojang has not added crawling or sneaking into 1.15 block tall areas. This is a feature on Java edition however.
Can confirm, I had the same problem on the latest version. Had two, sometimes even three shulkers generate on the same block.
