I just finished setting up Onkyo receiver on HA and everything works fine until I use iPhone app. When I click on receiver and click on source it shows only 3 sources selection insted of full list. I think issue is with the view on iPhone app. I can click little bit above list and it selects the source but it’s like you are selecting blindly. See screen shot below
Don’t think it’s an Onkyo issue, but more of a general iPhone app issue. I have the same with MQTT JSON Light components where i’m missing entries, yet they all show on a PC browser…
