I use this app for quite a time. I did not know that it shows the choice of voting power if you hold the button but you can change your power in the settings, too.

Anyway, I recently noticed, that I don't get upvotes anymore for writing comments with the app. Maybe it's kind of random and I noticed that other people get votes but for me, I had nothing since a few days. I'm not begging for the votes and I will use the app anyway because I like it, but maybe someone has noticed it too?
