What's going on with eSteem Surfer?

Since yesterday my "feed" on @eSteem Surfer is not showing the last post of the people I follow. Neither the trending page of the same service is appearing to be up-to-date...

I love this Steem frontend but I don't understand what is wrong with it.
I hope @good-karma or someone from @esteem can pass by this post and leave a comment below.
Is there any upgrade launched?
Thanks in advance.
