How to change number of words reviewed in android app?

I would like to ask how to change number of words reviewed on memrise android app. I have there only 10 words in classic mode but I would like to have at least 25 like here on pc version.

Check/amend your learning settings. You’re able to choose between 5/10/25/50/100 words per session. AFAIK you can’t have different settings for the web and app respectively.

ok thank you
