Hey Alex, I’m having the same issue as you. Were you ever able to get .onOpenURL working in watchOS? Works fine for me in iOS & shared code. Thanks.

Submitted a report via the Feedback Assistant (FB11859835). What's interesting is things were working fine this morning. I then added the "App Uses Non-Exempt Encryption" key to my info.plist and every build since then has has the issue. Removing the key didn't change things.
