The annoying thing is that every where in the documentation it says that you can add custom commands in Siri & Search, but that isn’t true anymore. But nowhere documented, so you bump in to a frustrating search on the how to of Siri shortcuts.
this forum is the first time that I find that others also have this problem.
For Adam1080 it will probably work again after renaming his shortcuts to the phrases he used before, but it is very annoying that this gigantic change is nowhere mentioned.
