There is a tag "PC", and the discussed topics do not occur on PCs.
It is ok to discuss bugs, solutions or workarounds. But uncontrolled gossiping is not very helpful.
Quite strange. Did again a flight tonight, no issues with the Simbrief and Navigraph integration. Flightplans, Charts, OANS, BTV, ..., everything was fine.
I can't confirm your problems on PC.
There have been plenty of updates.
I really don't understand, what you are talking about. There are definitely several bugs in the A350, but none of the ones you mentioned. At least not on a well configured system.
