Hi,
I've been away form the game for a while so I didn't get to test this again until recently, but it is still an issue on 1.16.201.
As further info to this, it only seems to happen with the character creator skins. A player with the old-style skin doesn't cause the same issue.
OK, I think you can close this and I'll open up a new ticket for the bedrock codebase in general after doing a little more digging tomorrow.
OK, maybe this is not a BDS issue, but a client issue then. I only have two users on the server so maybe we both get the freeze because we're both having the same client issue as we come into each other's view.
This isn't chunk generation lag (although that's a separate issue we've run into). These chunks have been long generated, and as it video clip shows it happens over and over for the same chunk.
Doing a little more digging, and it seems like the lag happens when the second player's character renders because it's close enough to mine (or vice versa).
Could it be a delay in downloading the other player's skin from the character creator?
If it helps, our client is Nintendo Switch.
I had this happento me today too. Was your original portal down below y=0? This is probably the same issue as MC-244742 on Java.
For reference, my original portal was at (129, -54, 9), which linked to (8, 73, 14) in the nether, but when I came back, a new portal was created at (65, -16, 124)
