User level: Level 1 (4 points)Why won’t my Apple Watch Series 8 connect to my iPhone 18 Pro Max? Could it be that the watchOS version is no longer compatible with the iPhone’s iOS?

Sure.
iOS 27.2 was released by Apple on October 26. Installing and using it seems to have resolved the issue for many folks.
This issue aside, you should always promptly update your Apple devices.

Various folks have complained about connectivity issues between iOS 27 iPhones and watchOS 26.6 Apple Watches. It’s highly likely Apple will update iOS in the next few days. Maybe that will resolve the issue.

Hi!
I also use IOS 27.2 on iPhone 17 Pro and my Apple Watch Series 8 wouldn’t update anymore. The worst part is that after several failed attempts to update the watch, I have reset it and now I cannot pair it anymore with my phone because I can’t update the software.
Does anyone else has this problem?
