It's known, that there are problems when the Server doesn't support SharedArrayBuffer (see #godot message by @placid ruin ) but luckily itch can handle it nowadays!

BUT

For me it works very well with my Android Device but it does not on iOS (see image for the error report). I tested on iPhone (safari & chrome) but I still get the sharedArrayBuffer-Error even thought it's correctly enabled via itch (and like i said: working nicely on android).

Is it known, that even with correct setup it just doesn't work on iOS?

It might be that IOS doesn't support it. The internet isn't clear about it. For certain, back in 2021, it wasn't supported, and could be enabled only after setting a flag.
CanIUse says that IOS safari does support SharedArrayBuffers, but I suspect the server flags required may not be set by itch

Damn. 😦 It's really sad. So far, GDevelop is the only engine which worked almost perfectly on android+ios. Not sure how they do it thought.. 😄 Never had to enable shared buffer for it. Maybe because it's not multi threaded...

Here are some extra information but I didn't have the time to try it out. In there a changelog is linked (https://developer.apple.com/documentation/safari-release-notes/safari-15_2-release-notes) which says Re-enabled SharedArrayBuffer for sites that use COOP and COEP securely to create an isolated environment. which sounds like since 15.2 of Safarai SharedArrayBuffer should be possible if COOP/COEP is there...whatever it is ... https://stackoverflow.com/questions/63306488/can-i-use-sharedarraybuffer-on-ios

So in theory, it should work
