Can't connect using Samsung Watch App on iPhone 11

[HavenC]

Sometimes has a pop up on the first screen but usually goes to this screen

I've also deleted/forgot the device in Samsung settings, and made sure its not connected to my apple watch.

I don't think it's possible, iphones arent supported as far as I know

Unfortunately in my experience, iPhones don't really work with smart watches other than the apple watch.
I find they keep disconnecting.
Like with the Huawei Watch GT3 I had. Some features are missing as well.
The apps don't really seem to be supported very well either.
I know Apple impose various restrictions on app developers, so some features will be missing.

I guess the more fitness watches maybe better supported like Fitbit

@HavenC  Unfortunately  ios has not been supported since Galaxy Watch 4 and the move to  Wear OS.   Some information here https://www.xda-developers.com/samsung-galaxy-watch-5-iphone-support/
