I am working on an XPUB in Pubcoder. It works on iOS 12.5.7. But on iOS 17.0.3 it behaves strangely in PubReader. Some times it does work but the next time I open it it doesn't work with sound. (I am using Howler.js for playing audio) I have made an HTML5 webapp and put it online. The webapp works perfectly in Safari also on iOS 17.0.3.
Can it be an issue in PubReader on iOS 17.0.3? Are you at Pubcoder aware of issues with PubReader on iOS 17.0.3?

Let me add that I have just tested my XPUB in PubReader on my Android tablet with Android version 9 - it works perfectly. So the problem can be narrowed down to PubReader on iOS 17.0.3.

It seems I have just succeeded to make my XPUB work in PubReader on iOS 17.0.3. My code was set to play a Howler sound sprite on load. I changed it so that it now plays a Howler HTML5 sound on load and then when that sound has ended the sound sprite plays 'on ('end')'. Then it all works from there.

Fingers crossed that it will keep working.
