iOS 16.2 Update Problems

Hey folks, I switched to Apple last year and got the iphone 13 pro max. My last iphone was the 4S soo i'm pretty new in the game.

After i updated to 16.2 my iphone is a complete mess. I'm a developer and I built my own home automation system which i used to control with the shortcuts app. I made shortcuts which send get requests to a server which then handles the processing of the devices. Works like a charme and still works now BUT, Siri doesn't work anymore in shortcuts. She simply doesn't recognise the commands anymore and tries to search in web. Example shortcut: studio lights off She understands "studio light off" or "studio lites off" she behaves like she's deaf or stupid or whatever. When I click the shortcut by hand, it works like a charm. But siri doesn't work anymore. I tried uninstalling the shortcuts app several times, I tried renaming the shortcuts to different names and even leaving them on the new names for at least 48 hours as apple support recommended to me.

next thing: Whatsapp. It crashes and hangs up randomly soo many times, I try to record a voice memo it doesn't work, i switch back to whatsapp from another app, and it's freezed, i can't scroll or click anything until i wait for like 5-10 seconds. This also happened to instagram but only once so far. I'm really really mad right now because I switched to apple, cz i was sick of bugs and I wanted a phone that just works. They kept telling me get an iphone it never has any problems. I'm ****** off. Apple Support told me they have never heard of these issues before YEAH SURE it's me 😅 I thought all iphones are the same? i don't run any third party apps, just a normal iphone with social media and shortcuts app. never dropped my phone always handled it with care. i'm so fed up I just want a phone with no bugs. last thing I wanna do is reset my device so please someone tell me you got the same problems with 16.2
