Render distance glitch

I’ve noticed this problem long ago since 1.16 came out, I guess, but since this bug still exist, I decided to write a report. This is SO annoying. On the photo below I’m running on iPhone 11 Pro Max, render distance is 36 chunks. From North to South everything is ok, but from West to East render distance is kinda cut off, I can’t see further than about 15 chunks, WHAT is that, Mojang?
