Playing an MP3 and using chord chart from Ireal

I used to be able to play an MP3 from my phone while looking at a chord chart in ireal pro. Is this option still available?

Yes, it's still possible but currently there is an issue with it.
Temporary solution: after you come back to the app, swipe up control center from the bottom of your screen and press play.
We will fix it soon.

Thank you. It is an essential tool for my gigs.
