Strong Password suggestion works just fine from a developer signed app on a development device. However, when we try to send it to QA for testing with our ad-hoc signed or even from TestFlight our distribution signed app, the Strong Password feature doesn't present itself. Our AASA file is up in production and is captured by the Apple CDN. Our associated domains entitlement has for example:
webcredentials:*.mydomain.com
Again, this works in development (did not need to use ?mode=developer) and our AASA file is up in production. Has anyone had issues testing the Strong Password or any Associated Domain feature in TestFlight?
