I find the same thing… The last one would update your model in MSFS from Blender in a few seconds and show you what your adjustments looked like. Or if you wanted to add a new model, just close out of Dev Mode for a few seconds then go back in and voila your model would be there. And sometimes that still works…?? But more often than not it doesn’t with this new update.
It would be so logical to use the Reload Asset button instead of having to reboot , a painfully slow process. ex hit build and then hit reload asset and the models and changes you just built would show.
But No…
