Some Issues with Multiplayer Connection

[Furioso]

I'm starting this thread to see if my issues are common before seeking help from 2K support.

I used to play private Civ6 games with my friends before R&F released. Back then I experienced no connection problems whatsoever. Recently I have started playing pubs, but is having some troubles with the connections every 2 or 3 games. Here are what I have encountered so far:

• When joining a room, sometimes I'm stuck in the "connecting to players" screen for a few minutes. While in some attempts I could join the room successfully after the wait, most of the time the "error joining multiplayer session" message pops up and sends me back to the lobby.
  
  
• If I return to the lobby by pressing the "cancel" button when joining a room, I can't join any other rooms in the lobby afterwards. Each attempt leads to the "error joining multiplayer session". I could join rooms again only if I restart Civ6.
  
  
• When waiting in a room, sometimes I can't see some of the players. In my perspective, their slots appear to be either "computer" or "open", but apparently the host or other plays can see there are indeed players in those specific slots.
  
  
• When I am desync'd from a game, I try to reconnect to the game by following one of the players in-game on Steam (by searching for them in the Steam Community tab). Sometimes however, when I click on the "join game" button, Steam leads me to a completely white screen instead of taking me back to the game.
  
  
• When other players are desync'd from the game and they tried to reconnect to the game, the game is stuck in a way that it's loading the next turn eternally. This can't be resolved unless the host leaves the game.
  
  
• Once, a game I'm playing appeared to be "split" into two. It was a 6FFA in which 3 of the players (not including the original host) desync'd in the same turn mid-way. We went on with the game but also got desync'd later. When I attempted to rejoin the game by following one of the players on Steam, I was led to another in-progress game with identical settings, but with only some of the players who got desync'd earlier.

Has anyone went into these issues before, or happens to know the solution to them? Thanks in advance for your attention.

EDIT: Forgot to mention the constant desync's everyone is having trouble with, but meh, you get the idea. ;)

Haven't had those issues so far... but i found out something about those nasty desyncs: they only hit me, when we're playing a map size "big" or "huge" - never on smaller maps. Mods doesn't matter and it also doesn't matter wether we are using internet or local network with a direct cable-connection. If anyone couds test and verify this...

playing with my gf on high-end computers, getting desync on both small and standard maps from day 100+ Never tried any bigger maps at all.
Saving the game, shutting it down, starting and loading again: and it works. sometimes until the end, sometimes for just a few rounds.
