Hello there.
I have numerous Construct 3 games playable on the browser, and they ALL have the same issue: Playing on Chrome mobile Web browser.
If I play my games from the mobile Firefox app, the audio starts playing normally after the player clicks the "Click here to fix the audio" button.
However, when I play the same games on the Chrome mobile app (latest version), the audio is messed up. After some research, I found out that Chrome has issues (or not) with "Preload audio" which prevents the audio from preloading on load and must be downloaded every time they have to play (UX impacted).
