I'm down sizing from the 12.9 to the new 10.5. One thing I noticed is when running iPhones, the 10.5 shows less content, even in 2x mode compared to the 12.9. It's mainly instagram that I run. I noticed it shows less content than even the iPhone 7 plus. I don't remember how the 12.9 started off as but I'm wondering if it's because the screen size is new and the app isn't optimized or just how things will be?
