What is the status of the bug keeping security app users from moving/reactivating the app on a new phone? I've found no recent information on this via search.

This is true of games which push hardware to its limits and have much more complex code that digs deep into hardware's capabilities. This is not a game, its code generator that as we can see can be run on a $4 key fob, it needs very basic system calls and even a dumbphone's level of hardware could handle it, so there is no need for optimization. The only thing I will give them credit for is that it seems they are building on top of another app, so that has its own peculiarities, however, the app is out for both iphone and android so the hole thing is still a bit sketchy.
