English Listening - Speaking

It’s really a great app but the point is the volume is too low ! And it doesn’t support air pods ! Can you help me?

First of all the app is great in general, I use it for grammar in particular, recently though there is something wrong with it that whenever I open any of the grammar Pages it suddenly crashes and shows me adjectives page only that no matter which page I open it always shows me the same page of adjectives which is really boring.. Please fix it as soon as possible and thank you.. Akira

There is something wrong on the voice recorder in(intermediate listening lessons - part 12 ) it didn’t work in some seconds from the center till the end
