iTunes remote button not appearing
I'm trying to use the remote app for my Mac and iPhone.
My iTunes is running version 12.9.4.94 and my iPhone is running version iOS 12.3 (both up to date; to my knowledge)
I'm having trouble connecting the remote app to iTunes on my Mac, I can get a code to appear on my iPhone but cannot get the remote button to appear in iTunes. I've got home sharing turned on but nothing appears.
Also, I read on here somewhere that some people had to open iTunes before generating the code from their phone, so I tried this but it made no difference either.
Has anybody got any suggestions please?
Cheers, Josh
