iOS 9/iTunes 12.3 not syncing app through devices

I've recently updated my IOS and ITUNES to the latest versions and when I sync my iphone is not syncing the apps automatically on my mac as it used to do before.

Is that a glitch of the new IOS?
Any easy solution to sort it out?

iPhone 6, iOS 9

Apps no longer will transfer from an iOS device to iTunes. See the note in this document.


Starting with iOS 9, the version of an app downloaded onto, say, iPhone7 may be different than the same app downloaded onto iPad. (It's called App Thinning.) If, however, the app is downloaded onto a computer then a universal app is saved which contains all variants. It can be tranferred to any compatible iOS device.


You can see this feature by comparing the file size of an iTunes Store app on a computer vs. an iOS device.

If you have Automatic Sync set on iPhone then there's nothing to sync.

Check on iPhone > App Store > Updates > ???

One more thing, do you have the same Apple ID on iPhone & Mac's iTunes and is authorised?

Yes, I have the same ID.
I know the iPhone update itself if that option is on, but I'm keeping the apps even on my iTunes library and when I sync my phone, the apps on iTunes used to update as well...till this morning!
I tried to cancel all the apps from my iTunes library and sync again my iPhone, but no app was transferred from my iPhone to the iTunes library...
It just sync everything but the apps!

Speaking only for myself, the apps don't sync. If I have "new" apps that I've downloaded on my iPhone, or existing apps that have been updated, when I click "Sync" in iTunes, those apps do not get transfered from iPhone to iTunes.


ETA: I have also tried the "transfer purchases" button in iTunes, still same result. It goes through all the steps and looks like it's syncing, but apps do not get from iPhone to iTunes.

I'm not sure I follow you. To add, I downloaded an app within iTunes store that has never been on my phone before. I was able to install it onto the phone, but again during the sync process, no new or updated apps are being transferred back to iTunes.


EDIT TO ADD:


I just plugged in my iPad Air 2 that I updated to iOS9 on the same day. Same behavior, no apps transferring. So this appears to be an iOS9/iTunes 12.3 issue and not limited to the iPhone 6.
