I've had newsblur premium for over a year now and my account has just decided to not be premium anymore. My initial premium upgrade was on April 26, 2013 and I can see that the recurring payment happened again on April 26, 2014 as expected.
It's been a couple weeks since I've checked Newsblur and when I looked today my account had reverted to free.

This is not good as Newsblur is pretty useless to me on free mode.
