    I have been testing Unity Tiny Version 0.32 and it works on Android (Chrome & Firefox), Windows (Chrome, Edge, Firefox), and iOS (Chrome). But it's not working on iOS Safari... In the documentation, it is written that the browser itself should not make any difference on iOS as they are all built on top of WKWebView (Webkit). I tried both wasm and asmjs, but there was no difference. I am running iOS 14.4 on an iPhone SE (Old one, not 2020).
    Why is only Safari on iOS not working? Am I missing something?

    Link to build that works everywhere except iOS Safari (https://uexilon.ch/UnityTest/MDU.html)

    Thanks for any help or clue about what's going on
    Kind Regards Michael

    Are there any errors from the browser console that we can look at?

    I would love to provide those or actually even see them myself, but Apple only allows remote console access through Safari on Mac OS afaik and I do not own a Mac. There are some discussed work-arounds on the internet to (maybe) getting it working on Windows :S I'll look into it... Not sure why it is so freakin hard for apple to let us access a log file on the device... Just Apple being Apple I guess.

    So I made some quick checks with BrowserStack. They have an (according to them at least... not emulated) iPhone SE first Gen but on iOS 11 instead of 14.4. And of course, it works there. Also tested it with other devices on Browserstack and they all worked but my personal iPhone still only displays an empty site :S
    I then went on and got the iOS proxy working so I can debug it using the chrome console.. Here is the entire Log:

    Code (CSharp):
    1.  
    2. Streamed scene with   4ms latency from Data/SubScenes/46b433b264c69cbd39f04ad2e5d12be8.0.entities    MDU.html:140
    3. Streamed scene with   3ms latency from Data/SubScenes/9fc0d4010bbf28b4594072e72b8655ab.0.entities   MDU.html:140
    4. HTML Window init.    MDU.html:140
    5. setCanvasSize True 568px 226px (backing 1136 452, dpi scale 2)    MDU.html:140
    6.  
    No errors are thrown... Nothing suspicious as far as I can see.
    Checking on the Networking side, I can see that safari indeed downloaded the HTML file and the font image.

    Well.. I... figured it out. A few months ago I was experimenting with webgl 2.0 on the iPhone and activated it in the experimental features tab of iOS Safari.. and left it activated... So there's the problem.. I turned it off and it instantly worked.
