End Gateways not spawning

From what I have seen, end gateway spawning has seemed to change, I haven't found an end gateway in a long time searching. I have been using Chunkbase.com and can't seem to find any. I don't know if this effects everyone or if it's just me, I just can't seem to find any other ones that spawn other than from the main island. I'm confused and need help.

And I don't see why 1.18 would break this but idk
