Same problem here. My device has "Associated Domains Development" option enabled. When I check my domain on Diagnostics, I get the green check mark, but on trying to tap the link somewhere, it opens the browser instead of calling my app. I don't have the associated file from website yet because I'm starting the development but I'm using the ?mode=developer parameter in the associated domains configuration.

I have the same problem, no matter the value for requiresOnDeviceRecognition. Also, it is a kind of random. Sometimes I have the error logs, sometimes it works well.
