Android App - Tactics trainer stuck

Please please please can you update the Android app so that the Tactics trainer does not get stuck. My app frequently gets stuck on a tactic and I can't move onto another problem no matter what I try. The same problem just keep repeating itself no matter how many times I click next problem or skip problem. The only way for me to get to a new problem seems to be for me to log onto the website on a computer and then the tactics trainer works fine. However if I unstick the problem on my phone, soon after the problem will stick again. 

Please can you fix this. The main reason I bought a premium membership was so that I could use the tactics trainer on my cellphone. 

Thanks chess.com staff for fixing this problem. The app works great on my phone now :)
