Hello, thanks for the warning you gave when I wrote when I wasn't exit of Minecraft Beta 1.16.0.66, I solved. I'm going to count a bug which is still in the Nether Update.

The bug happens when I was maked the End Portal and I breaked two blocks in the Y axis, I maked a mini room under the End Portal. The End Portal's black and green particles dissapears in the mini room, but the grey particles are visible. However there are differences both in Bedrock Edition and in Java Edition

• Bedrock Edition differences: In Bedrock Edition, in the mini room I was looked up the invisible particles, and when I tried to jump, the invisible particles the blocked the access, like if they are protected by invisible foundation
• Java Edition differences: In Java, when I accessed the mini room, the black and green particles there are invisible but I tried to jump, they don't lock the access

Please fix the End Portal bug in other updates. Thanks and bye!
