Here are the bugs that I've found since 1.15.. to 1.16.. versions of Minecraft PE

1. "Maps, empty maps & empty locator maps" are totally bugs!
2. "Dark Oak Sapling" does not grow when you apply or use the Bone meal to it.

My Suggestions for the improvement of MCPE

1. I suggest to make the "Polar Bear " works as the "Fox" as it become "white" when you spawn them in Antartic or snowy bioms, and when you spawn it to grass it will become color "brown", which is totally bear, and color "Black with the red eyes" for hostile Bear, and instead you put the name "Polar Bear" I suggest to just make it "Bear ", Like what you did to "Zombie Pigmen" you change its name into "Zombified Piglins"
2. for "Pig " I suggest to put an ears to it as what you did to "Zombified Piglins, Piglins & Hoglins"
3. I suggest as well to make Saplings for "Crimson & Warmped Stems"... mmm and instead "Stems" is it possible to make it "Logs"? maybe there's a purpose for it that I just want to know;

and lastly I really appreciate your works, everyone who works for its improvement, I know it's not easy to do such things yet I hope that you will do for the development of the game and thanks for reading
