iOS app sometimes launches a bit shrinked

    I have problem with my app for iOS built with C2

  • Webview engine(s):
    both Webview and Webview+

  • Framework/game engine (if relevant):

Hey @vixus
I had the same issue in my last app top and bottom area was having a black area it it was mainly in Bigger screens phones so i just switch to the canvas+ and it solved that issue. Give it a try.
