When I went to the Overworld from Nether, I'm going to sleep and it's happening that light is broken.
Confirmed in this beta.
Netherite upgrades can use only in the Smithing table, not crafting table and anvil. It still works in 1.16, not a bug found.
We have confirmed that this bug is happening something in my world with 14-16 chunks for Android. Please, add a vote for information, if you want to be fixed the lighting bug in future betas.
