manually updating software on an iPod Touch 7
I have attempted to download Spotify and Qobuz music apps to my iPod Touch 7, but the apps state they require iOS version 13 or 14 (respectively).
I assume there are such iOS versions of 13 or 14 available since the apps state the requirement, but iTunes says my Touch 7 has the latest software version (iOS 12.5.7).
Is there iOS versions 13 and 14 and how do I 'force' the updated to my Touch 7 in order to download and use these apps?
TIA
iPod, iOS 12
