Aquatic Update Has More Problems Than Before

I CAN TELL YOU ALMOST ALL ISSUES FOUND IN THIS AQUATIC UPDATE.

1: It crashes every TIME on Minecraft logo screen and will not happen after reinstalling.
2: When "Experimental gameplay" is on. The green zombies turn completely black and not often glitches out.
3: Continues to say that the XBox Account isn't signed in properly and it just said need to sign in and be able to join servers(ever since 1.1.0)
4: When adding resource pack in global resources. The game glitches out and stays flickering from the loading resources sign.
5: Hostile and other mobs don't spawn often
6: Minecraft gameplay over heats devices after a few minutes of gameplay even on IPad, MediaPad(Huawai), Oppo R7f. Etc
