Plugins are broken (yet again)
It's not the first time I had the problem that after an update, commands of multiple of the plugins just vanished (Audition had and has this problem, Illustrator is by far the worst at the moment, After Effects and Premiere was A LOT of back and forth until that was fixed by the support but I cared the most for that one).
Sometimes the issue seems to be as easy as the command name being written wrong in the ProfileInfo.json other times, I don't even know how they screwed up that badly, that commands can't even be found in the search anymore and both icons and descriptive text are missing in the UI.
Here are some examples:
Label "front camera" is shown, but action is not "available". It still executes but can't be changed to another button as it won't show up in the search.
Before you wonder "oh that's not logitech, that's Loupedeck". They use their software after they bought them. It's exactly the same and doesn't make a difference where you look. Both applications export lp5 file type for profiles and when you unpack/unzip them, there is even Loupedeck still mentioned in the ApplicationInfo.json
The only difference is that the default profiles expose way more commands in the Loupedeck application, so you can see better how many things are missing.
If you already had a working profile, the issue might not be that severe as the unnamed buttons are still working. But you can't rearrange then, you can't find them in the search, so you can't set them and working like that, with half of the icons missing, is a real pain in the butt:
In such cases, I only can guess which command does what action. The ProfileInfo.json does expose the command names but I can't change any icons as long as the "action (is) missing".
All in all, Logitech advertises it's products around software that is clearly not working as it should and every update is basically russian roulette as you can only upgrade and not downgrade to an older version.
So if you are interested in their products, especially for using it with your desired software I can only advise to skip it until such issues are not happen as frequently anymore (and I'm speaking about almost every second update they push).
