Lukas, enabling and disabling variants is a good feature but I think it's not really a solution for my issue. We already use two variants. One for dev, one for prod. Problem is when somebody is debugging application that already is set up for production variant. Then application is unintentionally registered to production variant with debugging token and the variant is messed up and it can stop working also for other devices registered to prod variant. Currently you need to find which device is badly registered and disable it in admin UI and it's not so easy to find it out. Thanks.
