This is regarding the RingCentral MVP app and the cell phone apps and their functionality for forwarding calls. As confirmed by two of your support reps and a support supervisor, the call forwarding from another forwarded call ( Ring in Order ) does not actually work, even from an admin setting. There is a completely different app available ( although it doesn't have all the functionality of the MVP app ) where this function does work.
If those non-functional call handling features are going to be available in the apps, at least put a notice of their non-functionality with a link to either a better explanation or a link to the download location of the alternate app where they do work.
Otherwise, an untold number of your customers are unknowingly making use of these non-functioning features and potentially missing any number of important, business critical calls.
