I will add to my comment above. Clicked on the link to try the Premium for free... there was no free trial option. Interested to see how quickly you will realize that you need to monetize in other ways. I also expect you pay lots to paid Contributors who’ve learned to take advantage of being paid by setting up templates that they can easily modify to write new articles without a requisite amount of effort. Not to suggest that there are not many excellent contributors. 
But, I suggest you’ve made a big mistake with your recent change. 

I concur with the above. Going to switch to other providers, Reddit and several other. Not sure what free article limit is but it is much too low for me to continue. There are other ways to monetize. I suspect you will see your active usership diminish rapidly.
