H1B visa stamping in October (Mumbai, India)

Hi, I’m currently employed in the USA on activate H1B, but the visa is not yet stamped on my passport. I have a US consulate appointment in October (at Mumbai). I reached out to the US embassy (support [at] ustravel [dot] doc) and they confirmed that they are processing all visa types at limited capacity. However, I’ve read multiple tweets about people facing difficulties/rejections at the visa centre because of Covid.

Has anyone recently traveled back to India to get H1B stamped?

What are the odds of not getting H1B visa stamped despite valid appointment?

Please advise.
