1.19 Issues with Portals and Elytra

I've been having some game-breaking issues since updating to 1.19 (Bedrock / PS4). 
Today, I mined in the nether for about 3000 blocks (~24000 OW) and made a portal. I went through it, and the "Loading Resources" screen froze, so I turned the game off after about 4 minutes of waiting (just in case it was extremely slow but still working).
I then restarted the game, loaded up the world, and ended up only 2000 away from spawn. There were no portals near me, I just sort of appeared there, 22000 blocks away from where I was supposed to be.
I decided to fly back to spawn/base, which started OK, then I noticed that my forward movement would stop in midair for a bit, maybe 3-4 seconds each time. This happened about 3 times over the span of 1500 blocks OW. The render distance (or rather, the actual rendering of the render distance area) is horrible on PS4, so I made sure I was at about Y=180 the whole time just to make sure I didn't hit any mountains, then all of a sudden I smacked into a tree, at Y=52. I was definitely at or above Y=180 when my X stopped moving while flying, and I just sort of showed up almost dead on that tree.
So I somehow again teleported two times: once bringing me 22000 away via portal with no possible way to have ended up there (other than a glitch, and no portal back to the nether), and again teleporting me down 130 blocks to crash land into a spruce.
Are either of these known bugs? I'd love to follow them if they already exist, because I use nether highways and elytras pretty often, as I think most users do.
