Notification Categories are deprecated!

I received this message yesterday when using my iPhone HA app. I have no idea what this means. I am wondering if someone can direct me towards how I can diagnose and resolve this issue or what exactly it means.

Thanks

Do you use apple.watch actions? There was a migration needed

Thanks. Yes, I use shortcuts and hence with my apple watch to open my garage door. I upgraded to IOS 15 a couple weeks ago. What type of a migration is needed? When I upgraded my iPhone to 15, I also upgraded my watch to the most recent update. Not happy about how shortcuts work now on my apple watch exactly, they added some extra step where I have to speak “allow”, but they have been working.

There is a migration guide here:

Thank you Tom. I had some actionable notifications(I love these things), that needed migration. I am curious though, why I started getting these messages now? Is there something I can do, to test my changes to see that I am current with their migration suggestions? Would I see this in my log after a HASS restart, or when the actionable notification is used?

In this article you see how to migrate it.
Basicly you move the categories as actions into your automation scripts

Because you updated the app and the way it handles actionable notifications has changed.
