Hindi (glitch in the app?)

[spjinks]

I'm really enjoying the new Hindi course, but I've hit a glitch on my tablet. I'm still working through Letters 1, 2, 3 and 4, but the 'match the pairs' activity sometimes fails to recognise a correct match, so I then have to go to my laptop to complete the lesson there. Any advice?

Same problem here, so annoying
