OPEN RAINBOW iOS14

Does anyone know if/when there will be an update to allow OPEN RAINBOW to work on iOS14? I know iOS14 is beta, but I still would like to be able to use open rainbow.  It does work sometimes, and other times not.  I cant access TELEPHONY settings and many times I try to make calls but it does not find the extension or user or even dial (even though it says it is).

Thanks...
