Thanks! Will look into this asap 👍

Should be resolved with v2.6.1

@raphaelhanneken @fenglee594 Are you guys sure this alpha channel issue applies to ios App icons as well? I just submitted an update 2 days ago with an App icon I generated using an older version - which includes alpha. The only thing iTunes rejects is alpha in the store icon (Marketing image). They allow alpha in app icons. Version 2.6.1 removes alpha from all icon sizes which is not required.
