The following text is an excerpt from this article (the last paragraph) :
But the dyspeptic diatribes came in spurts, and the president whipsawed between frustration and freewheeling meetings and golf outings, including one on Saturday with the president of the P.G.A. and the chairman of the Securities and Exchange Commission, according to two people familiar with his playing partners. Still, Mr. Trump was frustrated by the news media’s coverage of his rally in New Hampshire. He repeatedly complained about misleading pictures of empty seats, or that attendance at the arena had beat Elton John’s record crowd there, but no one was covering it.
I don't think the adverb still here expresses opposition nor does it express continuity, so what is its meaning then in this context?
