Hi, we just restarted in a seed we've already used due to 1.16.100. We wanted to use the new features. There is no bamboo at all. We've gone to the place where the bamboo forest was and there are pandas but no bamboo at all. There are not even the random bamboos in the whole jungle. Bamboo has disappeared.

So this gets stranger. I just made a new creative version of the seed - 819928115 and went over to the jungle on my phone. I was able to locate bamboo. My husband is on xbox one, and he's the one who originally looked and found no bamboo. I've given him the exact location of a piece of bamboo and he's going to try again. It might just be an xbox issue though.

Ah false alarm. He's just reloaded the world and gone back to that spot and has located bamboo. Sorry to have troubled you
