Absolutely awful. I have a laundry list of issues with this crusty update. We’ll see improvements and stability in July-ish when iOS 17 is right around the corner. Same bollocks every year. Definitely the worst is recent years.
My biggest complaint is that I can’t add my work address/location to Maps all of a sudden. It seems to be an issue only with my work address. Dropping a pin, setting my current location, choosing the facility name, etc. None of it works. There’s a disconnect between my contact card and Maps. Same address come up as two different locations. Siri took me to a third completely different location when I asked to navigate to work (before I deleted it to try to fix the above issue). Bombarded Apple support and Maps support last week with bug reports but I have yet to hear back.
You’re not alone.
