I am trying to set up a new U3 for my elderly father who struggles with multiple remotes and need to have a hidden device to hold a set of custom IR codes for a HDMI switching system, the previous U2 remote I used for this had the ability to hide a device while still using it's codes for macros and custom mapping. and it is in the documentation for the U3, but the option is not available in the app.
I need this to be available to minimise confusion, when will it be available again, otherwise I will probably have to return this remote.
