TestFlight Redemption Code

I have recently uploaded an application on TestFlight. I have added internal and external testers using non Apple ID email addresses. I know that these testers can test the build using the redemption code sent via invite email.


I have following doubts with TestFlight:

  1. Is it possible to install the app using same redemption code on multiple iOS devices having different Apple IDs?
  2. Is there a way to limit the installation on multiple devices using a single redemption code?


I would appreciate any suggestions and thoughts on this topic. Thank you.
