Hi,
We’ve managed to find a bit of a bug with the PlayCanvas editor. When launching to older iOS devices such as iPad Mini or iPad 2 from the PlayCanvas editor, the page will encounter an error and reload before the game is loaded.
We have tracked the issue to the use of let in the editor launch code. This breaks the PlayCanvas launcher on devices / browsers that do not have support for ECMA 6th Edition.
Below is a screenshot of the issue.
