I have a Philips Android TV (65PUT7374) and whenever I switch to a HDMI source, whatever app I am using in the TV closes on return. I have to reopen the app again and start using it. This gets a bit tiring especially when you are streaming. Is this the normal behavior or is there anyway to keep the app remain open while switching to a HDMI source?
Yes, this is normal behaviour. For the apps, changing source has same consequences as pressing home button
