@festusian Make sure your receiver is setup as an A/V device to control HDMI inputs. Mine could be added a few different ways but the others didn't give me control over changing the HDMI inputs. One of the confusing things to me is what device type to pick and why that's even needed. Apple TV can also be added as at least a couple different device types. If it generates different button mappings it would be more intuitive to me to select the device by name then ask me what type it is (aka how I use it).

Yeah, right now you can't make the activity buttons do anything but switch the remote's persona. They have said one of the top feature requests is to make it so that the activity buttons can send commands like you are looking for. It's also been said that the primary current focus is fixing bugs in the app. I fully agree that it is a frustrating experience right now. Even when there's something I know it can do I have a hard time remembering what to click on to get to the right screen. I have chosen to make the little 'i' (info) button perform the action of switching inputs since I don't really use an info button otherwise. So I have to select A, B, C then press i to get my A/V equipment to switch. Not as clean as desired but I'm holding out as it is promised to be fixed. Another useful feature that's been mentioned is adding support for alternate actions on long presses.
