These definitely look like Readium and testapp bugs, thanks for reporting. Your audiobook is probably guilty, but we should handle this case better. Could you confirm that you don't get this log with every LCP audiobook? I don't get it with a random one.

I'm sorry that this happens with all books of the same type ( Lcp )

also we tried on test app and get same issue Test app download from => https://github.com/readium/kotlin-toolkit/releases/download/3.0.2/test-app-3.0.2.apk

This is book you can try from your side (Lcp) book =>

I can reproduce the bug, thanks again!

[hishampro5]

@qnga sorry sir but Any guess when this might be fixed ; because we are blocked with this issue 🌹

[qnga]

I'd like to review carefully this piece of code because it's not the first time it's faulty, maybe this week. In the meantime, you can use the lcp-fixes branch if you're in a hurry.

[hishampro5]

@qnga Hi sir is there any update for this issue.

[qnga]

I rewrote the code, expect a release in the next few days.

@hishampro5 Could you confirm that the fix now in main resolves your issue before we do a new release? Thank you

[hishampro5]

@mickael-menu yes it's working fine with audio books (Lcp) we tested with testApp . Can i know when this might be released

[qnga]

It's done!
