Put my arm around my date, but no reaction?

Anonymous
We were sitting eating icecreams together when I put my arm around her shoulder.

Might I add that when I wanted to pay for the icecream she said "I'll pay for it" and then after I objected, she paid for it anyway, so I thanked her and told her I'd pay the next time.

I was expecting some sort of reaction, but when it didn't happen for around 20 seconds I figured it was a bad sign.
So I stood up trying to play it off.

Was it a bad sign?

On the one hand she let me put my arm around her, but on the other hand she didn't react at all.

Already whatsapped her a bit, haven't asked for a second date yet.
But she seems positive (fast reactions, fun reactions).
