Hi @Andreas_
1.: There will always be people who prefer the older to the newer and have difficulty dealing with change. There’s nothing you can do about it unless the people themselves do it. You go with it or leave it be.
2.: Regarding change, I also think that your company should seriously think about the latest software. Most young people don’t even know Win95 anymore. The comparison you’re making is like saying you can’t watch YouTube videos on a Nokia 3210. And the fact that the company doesn’t allow other browsers for “security reasons” but is still using Win95 is also a bit of an issue. Your IT manager should be able to handle the criticism.
3.: Most recently, streaming on the old web client still worked on Win7/IE11 (32bit). This was probably because SC bent over backwards and used a separate (older) streaming format (namely SMOOTH) specifically for this OS/browser combo. Not least because at that time some companies were still on Win7 and most security regulations did not allow other software (browsers) to be installed. But even there you couldn’t play encrypted content. Now DASH streaming is used everywhere, which is contemporary (you can find out something like that if you have some experience with trace tools). The fact that SC no longer supports this is probably because Win7 will soon be end-of-life and will no longer receive security updates (so your company should get a Win10 computer straight away). From my point of view, this is completely understandable (yes, I hear the screams of all Win7/IE11 users 😉 )
4.: It is the case everywhere that newer versions of software do not have a lot of backward compatibility, not least with Windows itself. The SC TV app only supports Android from OS5 and Apple from iOS9 (can be found in the respective app stores ). The effort and support to maintain the functions for all older OS versions would simply be too great.
5.: buy a bigger cell phone if it’s too small for you. I think everything from 4 inches (i.e. iPhone 4(s)/5(s)) should be sufficient and it doesn’t cost the earth anymore. In addition, I personally think that you can do better things during your break than watching TV.
