Can’t go to the End cities

I play minecraft on nintendo switch.(BE edition)
I defeated Ender-dragon and generated end gateway.
I could jump to the end city (outside) islands at that time. But I can’t go any more!
Just only jumping in central island even if I use ender pearl at gateway.
Ver 1.16.100 have this issue and recently version(1.16.200) still have...
Please modify this issue to go to the cnd cities again!
Or should I generate another Ender dragon and kill again??
