I can answer you on some points :
When I come to an Airport and ask for Jetways, it connects to the first Door. Also wrong. --> It connects to the nearest door on the jetway, always has benn like that and not a 350 issue but a flight simulator limitation, just get the second door closer and you will see it will use it.
It flies ok, but on the other side an old wisdom says "it´s not goeing, when its not a Boeing". There is that other developer who still develops those Boeing´s. We have to wait Centurys until they came out for MSFS 2024, but then they worked. Until now only ONE Update so far, not 10+. And guess what, Co-Pilot is sitting on the rigt side grinning and Jetways move to second Door as espected. Performance ++ and overall very satble flights. -->
I had time to spare for this one but honestly this just show your bias.
The 777F/200 fleet was released on May 19th and -300 on June 13th, I know it because I bought it that day.

Another subject, the 777 fleet is also subject to WASM crashes, I invite you to read their forums and Discord channels.
