Our nanny is still with us. We have a running conversation about comfort levels, precautions, levels of risk, etc... and some of those conversations have been difficult.
The kids did their summer camps and we had our family vacation in August. The kids are doing outdoor sports and playdates this fall. We (the parents) continue to try to allow as much normalcy for our kids, within what we consider to be acceptable/low levels of risk (and following all guidelines). We don't do anything with or for the kids that our nanny doesn't know about, and we maintain a social circle of folks we've been socializing with (all outdoors) since the Spring.
We talked candidly, more than once, about whether this job continued to be right for her. We all (she, me, my husband) agreed that if we were hiring a nanny right now she wouldn't choose us and we wouldn't choose her as a comfortable fit during the pandemic. We also agreed that as we're hitting the 4 year mark of her employment with us that we all would make compromises for each other that we wouldn't otherwise make because we would all prefer for this to work.
So we continue to work it through and it continues to be imperfect, though significantly less stressful than it was when I first posted. Navigating the personal risk and then the various dynamics of employment is really hard and there are days where I am sure each of us feels like it would be easier to give up and walk away. But the challenges of all of the uncertainly and fear around COVID-19 are true for everyone, regardless of situation. So she and we both acknowledge that this is about finding our way through this temporary nightmare as best we can, rather than expecting some perfect solution that doesn't exist.
That was a lot of rambling, sorry! To sum up, we are all doing our best and working our way through it.

Some days we want to quit but in the big picture we're all on the same side and we're trying to take care of each other.
