Today I noticed Weight & Balance was missing from the dropdown Toolbar.
The Slider for on/off was not showing in the custom toolbar (gear symbol), nor was the weight symbol in the main area.
Unsure of when this happened, maybe mid June? It was used and working early June for sure.
Maybe CU3 affected it?
Double checked the assistance options (there is none for this setting).
I tried a few different default ac, at a few different default airports, reset toolbar and assistance options; still no Weight&Balance available.
It wasn’t until I used ATC to send a fuel truck, that it showed up again.
Couple of different short flights and two msfs restarts, it remains in place and is working.
I suspect pulling up to a fuel station would trigger this reappearance too.
No bug report for now, maybe it was community folder related. I do use ToolBar PushBack
Give this a try if you find your missing the Weight & Fuel menu.
