Apple Watch 4 cannot approve BankID login after upgrading to iPhone 17 Pro Max

I have had a iwatch 4 for years. On it, I've been able to confirm login to the bank via an app called BankID in Norway. This has worked fine with Iphone XR, Iphone 15 Pro Max. I recently upgraded to Iphone 17 Pro Max. The message from the bank app to confirm login reaches both Iwatch and Phone, but it is no longer possible to approve from the watch as I get an error message. I then move to the phone and confirm the same question there and I am in.

So, there is obviously some kind of communication issue between the clock and phone. Anybody have any idea? Could it be that the watch is too old for the latest 17 pro max?

Yeah, Apple Watch 4 no longer receives watchOS updates from apple so that could be the problem

My brand new iPhone 18 Pro and Apple Watch Ultra 3 has the same problem. Noticed over the last week. Previously, when I used the iPhone 17 Pro Max with the exact same Apple Watch Ultra 3 I had no issues with BankID. Not sure if this is related to WatchOS27 or iOS27.

Currently my iPhone 18 Pro is running iOS27.2, and I'm about to update to iOS27.2.1 now to check if it's a compatibility issue. My Apple Watch Ultra 3 couldn't confirm BankID earlier, and after updating to WatchOS27.2.1 it still doesn't work.

You are correct about that. However, I now have iphone 17 pro max and iwatch 12 set up and even though it is working to confirm from the iwatch 30% of the time, I normally have to go to the phone to confirm. Both units have IOS 27.2

Must be something in the handshake between phone and iwatch I assume, but nobody seems to know and I am stuck.
