ipa file was produced by third-party application (not xcode).
I have real devices available to make 4/3.5 inch screenshots for iPhone and 9.7 inch screenshots for iPad.
But the essential screenshots on iTune Connect are 5.5 inch display iPhone and 12.9 inch display iPad (and I don't have the real devices for that).
If I photoshop screenshot for 5.5 inch and 12.9 inch according to its requiremnt as mentioned here: https://developer.apple.com/library/content/documentation/LanguagesUtilities/Conceptual/iTunesConnect_Guide/Chapters/Properties.html
For 5.5 inch iPhone:
- 72 dpi, RGB, flattened, no transparency
- High-quality JPEG or PNG image file format
- 1242 x 2208 pixels for hi-res portrait
- 2208 x 1242 pixels for hi-res landscape
For 12.7 inch iPad:
- 72 dpi, RGB, flattened, no transparency
- High-quality JPEG or PNG image file format
- 2048 x 2732 pixels for hi-res portrait
- 2732 x 2048 pixels for hi-res landscape
Will "Submit App Review" be ok? I mean whether somebody inside check the screenshot and make approval or not? Will they approve for app publishing? Or will they contact to make real-devices/stimulators screenshot?
