Please revise / update iTunes, it's horrible.
Well yes, it's horrible, but why does that matter in relation to the iPhone? I've not connected to iTunes in years, all backup is handled via iCloud and all app purchases are made on the device.
I had to stop using iTunes for my iPhone because my MacBook was too old to be upgraded to the required version of MacOS and iTunes. It was fine and I didn't miss using iTunes for a long time. I even restored the contents from iCloud after my phone was replaced due to a swollen battery.
That was until I found out that it didn't restore my music purchases correctly -- in a number of cases, it restored the wrong song from the same album. I ended up transferring my iTunes library from the old MacBook to a new one, and then syncing from there.
The old folks home, full of senile old farts pining for the way things were.
What does that make Usenet?
