The ender pearls defiantly travel slower compared to the 1.14.60 update, I not sure if the distance has decreased but I think it has. I thought it was just a hidden change to match the throw distance that Java edition has since bedrock ender pearls used to go further.
I only notice this when going through portals, I just fix it by placing a torch in the area and breaking it. I think in some cases its related to chunk borders but can't confirm
Smooth quartz stairs have outdated texture also. They still have borders like the regular quartz stairs.
