You cannot make an end portal

What???

The frames must all face inwards (towards the center).

I know that that's what i do every time it doesn't work.

are you sure you made the blocks from inside to the outside?

Can't reproduce. Portal frame blocks are directional, the easiest way to make a functioning portal is to stand in the centre of the 3x3 area, then place portal frames around you. Now all the frame blocks will be in the correct orientation, and your portal will be activated.

this is clearly still an issue

as you can see in the screenshot the portal is in position and is not working.

guys i just figured it out it works now.

guys there is a new issue to look at https://bugs.mojang.com/browse/MC-84384
