Letter jump list on android

I have been using the iOS app for several years but recently received an older Android device. Thinking the Android could become my dedicated new comic device, I loaded CLZ on it but noticed it doesn’t seem to have the alphabet jump list that the iOS version does. If I want to add to a series, I have to scroll all the way down to the series vs being able to jump to the letter and scroll from there. Is this just a difference in the OS or am I missing some setting?

This is indeed something that is only available on iOS (it is something you “get” from iOS as a developer).

Unfortunately we have not been able to create it on Android ourselves. On Android you can scroll a bit, and then “grab” the scrollbar (it is a bit difficult) to make it scroll quicker (but yeah you can’t go to a specific letter).
