Touch ID Issue with Sandbox Purchases

Question

Hi I was wondering if anyone else is having the same issue or has a fix for it.

When i'm trying to make an in app purchase in the sandbox for my app and i try and use touch id, it repeats the touch id alert three times then fails, i've tried using it in apples IAP demo app as well and get the same issue. is this issue only for sandbox mode? or has someone found a way around this?

Thanks in advance!

I'm pretty certain that Touch ID is not supported in the sandbox test environement (sic)" - Rich Kubota @ Apple.

I also see the behaviour you describe, and it has been this way for at least a year or two - it seems that TouchID is only supported by the production environment. I could not find any official documentation to support this however - there is no mention of it in, for example, Apple's In-App Purchase Programming Guide.
