Hi,

Thanks for reporting, needed more inputs on the bug, does it happen all the time ?

[anirudh-softprodigy]

yes, it does happen all the time. Will this work with mp3 files ?

[unicorncoderforever]

actually it is working on my phone, your OS looks like 11

[unicorncoderforever]

I haven't implemented the newest writing external storage way, so that might be the reason, but I will look into again

[unicorncoderforever]

it might take quite sometime for me to implement can check in lower android versions to cross check whether that is the issue

[unicorncoderforever]

pushed the temporary change, let me know whether its working

[manikandan-artium]

not working, I am also facing the same issues
