Tactics on Android app

Hi all,

Has anyone else found that doing tactics in the Chess.com app on Android seems much harder/ harsher rated than doing tactics online? It seems like every time I lose in the app I drop 13 or 14 points, and the most I ever win is about 4, and it's usually only 1!

However, whenever I play online, I often score in the 7-13 range, and losing tends to be anything between -1 and -9 (very occasionally up to -13). I know that in theory they're the same tactics puzzles and ought to be scored the same way, so it doesn't make any sense.

I thought I was imagining it, but it occurs with such consistency that I don't believe am.

Has anyone experienced similar or has an explanation?
