Plus subscribers losing their Plus access during plugin rollout?

At my company, I’ve heard of one person who has a standard Plus subscription but as of this morning has lost it and seems to have been reverted back to the free plan.

Somewhere on Twitter, I have seen one or two others who reported the same issue and they were advised that this could be a bug of the Plugins rollout and that the Plus subscription should come back soon (presumably together with the plugins access).

I haven’t seen a post on here about the issue, so I wonder if anyone else has seen it and whether anyone knows more or has a workaround to fix it?
