Pronunciation doesn’t work

On my iPhone X set to German system language pronunciation doesn't seem to work. I see it change from the button to this waveform type of thing but don’t hear anything. Apart from that the app looks nice. I like it.

Any chance to see this bug fixed soon?

Developer Response ,

Love it

It’s a fun way to learn new words. The App looks great and has some pretty unique things like “Smile to Like”. Maybe some App localizations.
