Bad, bad, updates
I had taken a break for a while then redownloaded the app. Wow, so many changes. And not one for the better. I understand the need for an app to generate revenue and am not opposed to throwing $ every now and then to an app, but the methods now used renders the app useless. The time to regenerate is about 5x too long, and cost of gems is so ridiculous I would rather purchase a program. You would be better scrapping it all and placing ads or charging a one time language fee. I will try in another month or so to check for improvements, but in the meantime will look for a different app.
