Big fan, one problem

I love this app, however it only plays back recordings through the ear piece of my phone. Coming from iPhone 11 Pro

New update is required.

Horrible app does not worth the price. Last time it was updated was 2 years ago. Check the latest version update if it’s not then don’t waste your money. I want my money back too if possible.
