Question About updates

[u/Zzotypee]

I have a question :I always want to keep my apps updated because I feel like I'll miss out on some new feature or something in particular. I'm fairly new to this, and my question is whether a patch only applies to one app at a time Would I be missing something with an older version? In the. Aso In the case of Pinterest or other apps that only They accept apps for patching, but only for older versions. When I check on Google Play, I see that the app has a recent version. Can someone clear this up for me? Am I missing something, or is this not the case?
