Chunk loading is slow, and can cause a problem, but it is still a problem in 26.3. I think this should be resolved as soon as possible, as this disrupts a lot of the gameplay if you are using an Elytra.
I also had this happen, and playng in 26.3. I looked up as the chunks were generating, and it did that.
Also, I forgot to say that I could not move.
No, I am not using any add-ons, but I will see if I can cen get a video.
I also had that problem, but I play on switch.
No, but it is not fixed. I played just today and the issue was not fixed.
Yes, I had this happen on my switch in 26.3.
