Thank you again,

Unfortunately the game is made for mobile devises, and after discussing this with my partner we do not plan to release an online version (at least it is not something we are ready to do at the moment).

To help illustrate the problem;

Here is a screen capture of the level complete screen on Chrome (no errors):

And here is the same moment in Safari (many UI elements have disappeared or are flashing in and out):

Both on the same macOS machine, same build and construct version R225.

The game is already available in early access on google play, if this helps.

Cheers!

Thank you both,

Sorry for the unclear post I now see my error in mixing macOS and IOS.

Considering that I have severe graphical issues, that "minimal-ui" and the errors I presented are not significant. Along with the fact that the game otherwise functions fine on Google Chrome browser (both on Windows PC and macOs).

What differences usually causes issues between the two browsers/platforms?

What options, other than the debug log and play in debug mode, could I explore to get to the bottom of this.

MyApp: Nov. 22nd, fails to execute in Safari.

However same app runs, unmodified, correctly and without errors in Google Chrome on same Mac.

General behaviour in Safari::

- Error in safari web inspector console (see below)

- not all graphic assets displayed

- some graphic assets are blinking in and out

- some displayed assets are not in right position

- very, very, very slow execution

My environment is::

MacOS High Sierra 10.13.6

Chrome on Mac Version 87.0.4280.67 (Official Build) (x86_64)

Safari Version 13.1.2 (13609.3.5.1.5)

Using the latest stable Construct 3 release R225
