A bug when working with LINGQ on my iPad

When I use Lingq on my iPad and click on a word, I get information on this word and a possible translation, or a hint. I often try to find other information on that word by consulting an online dictionary. But when I come back to the word in Lingq by clicking on it again, nothing happens, I cannot come back to the information on the word. I have to click first on an other word, and only then I can come back to the first word. I hope that the developpers can do something about this.

Can you please record a video and send it to support(at)lingq.com? Thanks!
